Peterson underwent surgery Thursday to repair a sports hernia, ESPN.com reports.

Analysis: Now we know why the Vikings started listing Peterson -- who did not miss a game this past season -- as having an abdomen ailment, starting in mid-December. The Vikings expect "no long-term concerns" as a result of the procedure and that's a believable assessment, given how incredibly Peterson bounced back in 2012 from a major knee injury that he sustained late in the 2011 campaign.

Peterson carried the ball 22 times for 99 yards in Saturday's playoff loss to the Packers.

Analysis: A respectable effort for Peterson to close out the Vikings' season, but with QB Christian Ponder inactive Saturday and Joe Webb behind center, the team's offense faced an uphill battle all evening. That Peterson came within nine yards of Eric Dickerson's single-season record of 2,105 rushing yards after coming back from a devastating knee injury remains stunning and at 27 years old, the running back's future is bright. Entering the 2013 season, further removed from his knee woes, Peterson figures to top most fantasy draft boards.

Peterson (sore abdomen) was a full participant in practice Friday and is listed as probable for Saturday's playoff game at Green Bay.

Analysis: Even though Peterson missed practice Wednesday and was limited Thursday, there was never any doubt he'd play this week. His full participation in Friday's practice show his injury isn't a worry.

Peterson (sore abdomen) returned to practice Thursday after sitting out Tuesday and Wednesday, ESPN 1500 am Twin Cities reports.

Analysis: Peterson has indicated that his abdomen issue is no concern and there's no doubt that he'll be available Saturday against the Packers, who he torched for 210 rushing yards in Week 13 and 199 in this past weekend's regular season finale.

Peterson (abdomen/groin) sat out practice again Wednesday, the St. Paul Pioneer Press reports.

Analysis: There's little doubt, however, that Peterson will be out there Saturday against the Packers, with the larger issue for those drafting Peterson in playoff pools being the question of the Vikings' chances of playing more than one postseason game. They are clear underdogs this weekend on the road against the Packers.

Peterson (abdomen/groin) sat out Tuesday's practice, 1500 ESPN Twin Cities reports.

Analysis: Peterson was rested during practice for the majority of last week and managed to put up 199 yards, so it appears safe to say he'll be ready to go for this Saturday's Wild Card game. Peterson had a season-high 34 carries in Sunday's win over the Packers and should see a substantial workload in this weekend's rematch.

Adrian Peterson: Falls Nine Yards Shine of Rushing Record

Peterson (abdomen/groin) carried the ball 34 times for 199 yards with a touchdown and added a two-yard TD catch in Sunday's win over the Packers.

Analysis: Peterson fell just nine yards shy of Eric Dickerson's single-season record of 2,105 rushing yards, but his outstanding effort caps a phenomenal comeback story that has taken the running back from a serious injury (sustained just over a year ago) to leading the Vikings to a 10-6 season and a playoff berth.

Peterson (abdomen/groin) will play Sunday versus Green Bay.

Analysis: Peterson needs 208 yards rushing to set the single-season record, which isn't a stretch considering the Packers allowed him to scamper his way to 210 yards in Week 13. Perhaps his abdominal strain will hinder him, as well as a determined Packers frontline, but he is a must-start as always.

Peterson eyes record books

In his "Week 17 Predictions" analysis, Elliot Harrison notes, "the Packers' run defense allows 111.9 rush yards per game. Peterson has averaged 155.4 since Week 7." FULL WEEK 17 PREDICTIONS

Analysis: Peterson should always be considered a must-start, and with just 208 yards separating him from the record, expect another solid performance.

Peterson (abdomen/groin) returned to practice Friday and is listed as probable against Green Bay. "He feels pretty good, feels better than he did (last) Friday this time," head coach Leslie Frazier told ESPN 1500 am Twin Cities. "So, I don't think we have to go into it thinking about limiting his carries or anything like that. I think we go full-speed ahead. That's what he wants. That's what our doctors are telling me. He's ready to go."

Analysis: Peterson missed the last series of last week's win over Houston with abdominal soreness, but the move was seen as mostly precautionary. He should start this week and get plenty of carries with a playoff spot on the line.

Peterson (abdomen/groin) did not practice Thursday, but head coach Leslie Frazier said there's no concern about him playing this week against Green Bay, ESPN 1500 am Twin Cities reports.

Analysis: Peterson missed the last series of last week's win over Houston with abdominal soreness, but the move was seen as mostly precautionary since the Vikings had a large lead. He may not practice all week, but the injury isn't seen as holding him back at all this week.

Peterson (abdomen/groin) will not practice Wednesday, ESPN 1500 am Twin Cities reports.

Analysis: Peterson missed the last series of last week's win over Houston with abdominal soreness, but the move was seen as mostly precautionary since the Vikings had a large lead. He may not practice at all this week, but is expected to play against Green Bay with a playoff spot on the line.

Peterson will likely be limited in practice this week as he continues to deal with abdominal soreness, 1500espn.com reports.

Analysis: While it's worth noting that he is banged up, there is nothing to suggest that the NFL's leading rusher is in any danger of missing Sunday's game against the Packers.

Peterson falls short

Peterson totaled 25 carries for 86 yards rushing and had one catch for four yards during the Vikings win over the Texans on Sunday. WATCH HIGHLIGHTS

Analysis: The performance was just the second time Peterson failed to score double-digit fantasy points this season.

Adrian Peterson: Misses Last Series With Sore Abdomen

Peterson had 25 carries for 86 yards in Sunday's win over Houston. He missed the final series due to abdominal soreness, ESPN 1500 am Twin Cities reports.

Analysis: Toby Gerhart rushed for a touchdown with Peterson on the sidelines, so his absence stung for his fantasy owners. However, the Vikings were comfortably ahead, so he was likely held out as the team played it safe. Still, check Peterson's status early next week.

Peterson (abdomen/groin) will play Sunday in Houston.

Analysis: Peterson has seemingly dealt with a minor injury concern each week in practice this season, only to run amok on opponents and ask questions later. With the fantasy playoffs ongoing, make sure he's in your lineup as always.

Peterson nearing record

In his "All-22" analysis, Bucky Brooks notes, "The four-time Pro Bowler has been sensational in 2012, rushing for 1,812 yards and 11 touchdowns in 14 games, and he's done it in spectacular fashion, notching nine 100-yard games, including eight straight since Week 7. Most impressively, he has posted 20 runs of 20 yards or more, including eight runs of at least 40 yards." READ: ALL-22

Analysis: Peterson will face one of his tougher tests this week against a Texans defense which has allowed just three rushing scores this season. That said, the back has proved he is matchup-proof and his quest for the rushing record is just one more incentive.

Peterson (abdomen/groin) was a full participant in Friday's practice and is listed as probable against Houston. "[Peterson] did a good job, went through everything in practice," head coach Leslie Frazier told ESPN 1500 am Twin Cities. "So, he should be fine for Sunday."

Analysis: Peterson missed practice on Wednesday and Thursday, but it was to give him rest rather than due to a significant injury.

Peterson (abdomen/groin) did not practice Thursday, ESPN 1500 am Twin Cities reports.

Analysis: Peterson has missed two consecutive practices, but says he'll play Sunday. It sounds like he's just getting some time off and neither ailment is a serious concern.

Peterson (abdomen/groin) did not practice Wednesday, but it was mostly due to a day of rest, ESPN 1500 am Twin Cites reports.

Analysis: Peterson is listed on the injury report with groin and abdomen ailments, but neither should be a worry since he didn't report a setback after last week's game. He missed a day of practice last week with a sore abdomen and then rushed for 212 yards.

Adrian Peterson: Another 200-Yard Game

Peterson (abdomen) had 24 carries for 212 yards and a touchdown Sunday against the Rams.

Analysis: Peterson had a fairly good fantasy day on his 82-yard touchdown run in the second quarter alone but he continued to pad his numbers throughout the day. It was his fourth career 200-yard game and his 1,812 rushing yards this season are a new career-high. It's been an absolutely dominating season for Peterson, who is now 294 yards shy of breaking Eric Dickerson's single-season rushing record of 2,105, set in 1984. He has rushed for at least 100 yards in eight straight games and has been a fantasy marvel for fantasy owners who were not overly concerned about the torn ACL he suffered less than a year ago.

Peterson rips off big run

After being held in check the first quarter, Peterson ripped off an 82 yard touchdown run against the Rams. FOLLOW WITH GAME CENTER

Analysis: The back now has 90 total yards in just over two quarters of action.

Peterson (abdomen) is active for Sunday's game at St. Louis.

Analysis: As expected, Peterson will continue to play through a minor injury concern. Even though his opponent, the Rams, have held three consecutive backfields to less than 100 yards, they have allowed three touchdowns to opposing running backs during that span. Still, he'll strive for his eighth 100-yard outing in a row.

Peterson posting big totals

NFL.com's "10 Mind-Blowing Stats" for Week 15 notes, "Peterson has more rushing yards in the last seven games (1,101) than the Jacksonville Jaguars (1,068), Oakland Raiders (1,055), Dallas Cowboys (1,038) and Arizona Cardinals (1,021) have as a team this season." READ: 10 MIND-BLOWING STATS

Analysis: Though the Rams defense only allows an average of 110 yards rushing per game, the unit has allowed the fourth-most (15) rushing scores this season. Peterson has proven he is matchup-proof, so make sure he's in your lineup.

Peterson (abdomen) was limited at Friday's practice, but is listed as probable against St. Louis, ESPN 1500 am Twin Cities reports.

Analysis: He missed practice Thursday and was limited both Wednesday and Friday, but this sounds like a minor ailment that isn't something to worry about. He's expected to start this week against the Rams.

Peterson (abdomen) was not at Thursday's practice, the St. Paul Pioneer Press reports.

Analysis: Peterson likely just got a day of rest. Peterson has been on the injury report several times this season (shoulder, ankle), but he hasn't been hindered in games. We suspect this injury is another minor ailment since he was able to practice Wednesday. Still, check to see if he's able to practice Friday just to be safe.

Adrian Peterson: Limited Wednesday With Abdominal Injury

Peterson was limited in Wednesday's practice due to an abdominal injury, ESPN 1500 am Twin Cities reports.

Analysis: Peterson has been on the injury report several times this season (shoulder, ankle), but he hasn't been hindered in games. We suspect this injury is another minor ailment since he was able to practice, but watch his progress during the week.

Adrian Peterson: Posts Another Big Game

Peterson had 31 carries for 154 rushing yards and two touchdowns, as well as two catches on two targets for 16 receiving yards Sunday against the Bears.

Analysis: Peterson's magical season continued Sunday, as he was able to cross the 100-yard mark before the end of the first quarter. He now has exactly 1,600 rushing yards on the season and has hit the century mark in seven straight games, scoring eight touchdowns over that span. A Week 15 matchup against the Rams shouldn't dampen expectations for the streak to continue.

AP doubles up early

Peterson is off to a stellar start, scoring twice behind 74 yards rushing against the Chicago Bears with just over six minutes played. FOLLOW WITH GAME CENTER

Analysis: With Percy Harvin out, this is just the beginning for the veteran running back.

Peterson leading the way

NFL.com's "10 Mind-Blowing Stats from Week 14" notes, "Peterson leads the NFL with 1,446 rushing yards, the second most in a single season of his career. To reach 2,000, Peterson needs to average 138.5 rushing yards in his final four games. He has averaged 157.8 in his last six games. The Vikings close the season against the Bears, Rams, Texans and Packers; all four are in the upper half of the league in rushing defense." READ: MIND-BLOWING STATS

Analysis: Peterson posted 11.80 points against the Bears in Week 12, a performance which could have been better had he not lost a fumble during the contest. Expect him to carry a heavy load with Percy Harvin now on the I.R.

Peterson fully practiced Friday and isn't listed on the injury report this week against Chicago. He was given the day off Thursday by head coach Leslie Frazier.

Analysis: Peterson has been playing with minor ailments the past few weeks (shoulder, ankle), but it hasn't limited in him games. He looks as healthy as he's been all season heading into this week's game against Chicago.

Peterson was given the day off Thursday by coach Leslie Frazier, the Minneapolis Star Tribune reports.

Analysis: Peterson has been listed on the injury report with shoulder and ankle concerns this season, only to obliterate all comers each Sunday. His owners should not be concerned in the least, as the NFL's rushing leader with 1,446 yards will be out there Sunday against Chicago.

Adrian Peterson: 210 Rushing Yards Sunday

Peterson (shoulder) had 21 carries for 210 rushing yards and a touchdown, as well as one catch on two targets for 10 receiving yards Sunday against the Packers.

Analysis: A downright dominant game for Peterson, who scored on an 82-yard run in the second quarter to give the Vikings a 14-10 lead. Peterson has now broken the 100-yard mark in six straight games, scoring six touchdowns in that span. A seemingly tough matchup awaits in Week 14 against the Bears, although Peterson rumbled for 108 yards and had 30 more through the air against them in Week 12.

Peterson sets career mark

Peterson carried the ball 21 times for 210 yards and a score against the Packers on Sunday. He also added ten yards receiving. WATCH HIGHLIGHTS

Analysis: A bulk of the veterans yardage came on a career-long 82 yard run. His 28 fantasy points should hold to lead all fantasy backs in Week 13.

Peterson sets career mark

Adrian Peterson had a career long 82 yard touchdown run in second quarter action against the Packers. FOLLOW WITH GAME CENTER

Analysis: The veteran now has 126 total yards and a score in the first half alone for the Vikings.

Harvin OUT

Vikings wide receiver Percy Harvin (ankle) was officially ruled out on Saturday. FULL SUNDAY INJURY ROUNDUP

Analysis: Adrian Peterson should be called upon to carry a heavy workload as the Vikings lone offensive weapon today.

Peterson (shoulder) will play Sunday in Green Bay.

Analysis: Despite enduring minor ailments throughout the season, Peterson easily leads the league in rushing by nearly 200 yards. His opponent, the Packers, have yielded well over 100 yards on the ground in each of the past two games, so it appears he has quite the friendly matchup in Week 13.

Peterson to carry the load

In his Week 13 "Like/Dislike" analysis, Adam Rank notes, "Adrian Peterson leads the NFL with 1,236 rushing yards. Peterson has rushed for a TD in seven of his last eight games against the Packers. Peterson has rushed for at least 100 yards in five consecutive games to tie a record held by Robert Smith." READ: LIKE/DISLIKE

Analysis: The Rams are tied for third-worst in the NFL, allowing 14 rushing touchdowns this season. With Percy Harvin sidelined, expect Peterson to carry a heavy load.

Analysis: Peterson suffered a shoulder strain in Sunday's loss at Chicago, but it doesn't look like anything to worry about.

Peterson (shoulder) was a full participant in Wednesday's practice, the team's official web site reports.

Analysis: Peterson suffered a shoulder strain in Sunday's loss at Chicago, but it doesn't look like anything to worry about.

Peterson suffered a shoulder strain in Sunday's loss at Chicago, but head coach Leslie Frazier said it shouldn't affect his availability for this week's game at Green Bay, ESPN 1500 am Twin Cities reports.

Analysis: We'll need to see if he's able to practice Wednesday, but this sounds minor and Peterson is someone who's been able to play through minor ailments.

Peterson (ankle) had 18 carries for 108 rushing yards and six catches on seven targets for 30 receiving yards Sunday against the Bears. He also lost a fumble for the second time this season.

Analysis: Peterson was held to only 25 rushing yards in the first half, although he was able to pick it up in the second to tie Robert Smith for a Vikings-record fifth straight 100-yard rushing game. One negative is that he failed to score a touchdown after doing so five times in the prior four games. It doesn't get a whole lot easier next week against a Packers' defense that was ranked 10th against the run heading into Sunday.

Peterson carries the load

Peterson totaled 18 carries for 108 yards, adding another 30 yards receiving against the Bears on Sunday. WATCH HIGHLIGHTS

Analysis: It was a solid performance from Peterson, who was the focal point of a stout Bears defense with Percy Harvin missing the game.

Harvin is OUT

Vikings wide receiver Percy Harvin (ankle) was officially ruled out on Saturday. He didn't make the trip to Chicago. FULL INJURY ROUNDUP

Analysis: With their top receiving threat sidelined, Adrian Peterson should be the focus of the Bears front, so temper expectations.

Adrian Peterson: (Ankle) Active Sunday

Peterson (ankle) will play Sunday in Chicago.

Analysis: Following a bye week in Week 11 and a full practice all week, Peterson will take the field versus a staunch Bears rush defense (95.2 yards per game). Start him as you normally would.

Peterson setting new marks

Analysis: Peterson will face a tough Bears defense Sunday, but he's the best running back in the league and pretty much matchup-proof. He's a must-start in nearly all cases.

Peterson (ankle) was a full participant in practice Wednesday, 1500 ESPN Twin Cities reports.

Analysis: Peterson leads the league in rushing by a whole 123 yards, which ensures his status as a must start, even against a Chicago rush defense Sunday that has yielded a mere three touchdowns and 95.2 yards per game in 2012.

A grand jury in Harris County, Texas found no probable cause for Peterson's July arrest at a Houston nightclub and he won't face any charges, the Minneapolis Star Tribune reports.

Analysis: Peterson had been charged with resisting arrest during an incident at the bar. However, Peterson denied he'd grown belligerent when asked to leave and said he was treated unfairly when police tackled and punched him during his arrest. It was always a long shot that Peterson would miss playing time over the incident, but now this isn't a worry for his fantasy value.

Peterson continues to surprise

In his "Move the Sticks" analysis, Daniel Jeremiah notes, "Over his past four games, Minnesota Vikings running back Adrian Peterson has rushed for 629 yards and five touchdowns while averaging 7.7 yards per carry." READ: WEEK 10 NOTES

Analysis: Peterson has now posted four straight games of 120 yards or more rushing. With a Week 11 bye and a matchup against the Bears in Week 12, it might be some time before he posts another dominant performance like this one.

Peterson continues tear

Peterson carried the ball 27 times for 171 yards and a touchdown against the Lions on Sunday. WATCH HIGHLIGHTS

Analysis: Peterson has now posted four straight games of 120 yards or more rushing. With a Week 11 bye and a matchup against the Bears in Week 12, it might be some time before he posts another dominant performance like this one.

Peterson (ankle) had 27 carries for 171 rushing yards and a touchdown, as well as three catches on four targets for five receiving yards Sunday against the Lions.

Analysis: Peterson is on a tear lately, rushing for at least 120 yards and a touchdown in four straight games. Unfortunately for fantasy owners, the Vikings on a bye in Week 11 so they'll have to find an alternative to plug into their lineups.

Adrian Peterson: (Ankle/Illness) Active

Peterson (ankle/illness) is active for Sunday's game versus Detroit.

Analysis: After enduring a stomach virus Thursday, which kept him out of practice, Peterson will suit up as expected. Start him as you normally would against the Lions' 14th ranked rush defense (106.3 yards per contest).

Adrian Peterson: (Ankle/Illness) Probable For Sunday

Peterson (ankle/illness) is probable for Sunday's game against Detroit, Vikings.com reports.

Analysis: Peterson's health isn't really a concern right now. Needless to say, he's a must-start against Detroit.

Peterson participated in practice Friday after missing Thursday's session due to an illness, ESPN 1500 am Twin Cities reports.

Analysis: Peterson left the team's facility Thursday with a stomach illness, but it sounds like he'll be healthy by game time on Sunday.

Coach Leslie Frazier said that he hopes to have Peterson (illness) back at practice on Friday, the Minneapolis Star Tribune reports.

Analysis: Peterson left the team's facility Thursday with a stomach illness and did not practice, but while that's a less-than-ideal situation for Peterson, it's less troubling from a fantasy standpoint than if he had suffered any injury setbacks.

Peterson (illness) won't practice Thursday, the St. Paul Pioneer Press reports.

Analysis: We'll have to see if Peterson is able to return to practice Friday, but the fact that he is feeling under the weather is less troubling than if the Vikings had reported a setback with his ankle or knee.

Peterson (ankle) practiced fully Wednesday, the Vikings' official site reports.

Analysis: Peterson -- who ran for 182 yards on 17 carries in Week 9 -- was limited at practice last week before resting Friday, so his full participation Wednesday is a great sign that he is fully past his ankle woes.

Peterson (ankle) had 17 carries for 182 rushing yards and two touchdowns Sunday against the Seahawks. He also had three catches on four targets for 11 receiving yards.

Analysis: Peterson did most of his damage in the first half, rumbling for 144 yards before halftime. He was fairly limited in the second half though, gaining only 38 yards, 28 of which came on a single play. Fantasy owners don't really care when the yards or scores come from, just that they do, and they certainly did on Sunday. Peterson now has at least 120 yards and a touchdown in three straight games and next faces a Lions' defense that was ranked 16th against the run heading into Sunday.

Peterson continues to thrive

Peterson totaled 17 carries for 182 yards and two scores against the suddenly porous Seattle defense on Sunday. The veteran also added 11 yards on three receptions. WATCH HIGHLIGHTS

Analysis: AP's 31.30 fantasy points were bested only by Doug Martin's franchise record breaking day against the Oakland Raiders.

Harvin, Peterson are active

Percy Harvin and Adrian Peterson are active for today's matchup against the Seahawks. FULL PREVIEW

Analysis: The pair will have work cut out for them against the stout Seattle defense, so temper expectations.

Peterson (ankle) will play Sunday at Seattle.

Analysis: Peterson was limited in practice both Wednesday and Thursday, before sitting out Friday to gain a bit of rest. Since the beginning of October, he has played through a sore ankle and produced prime fantasy output, which should be the case once again in Week 9.

Peterson misses practice

Running back Adrian Peterson was absent from Friday's practice, 1500ESPN.com reported. Peterson has been dealing with an ankle issue in recent weeks, but he hasn't missed any games. He enters Week 9 leading the NFL with 775 rushing yards. He was limited in Thursday's practice, and it's possible the team is just being cautious with their star. FULL REPORT

Analysis: Expect Peterson to be available on Sunday. He's been limited in practice the last few weeks in what looks like will be the trend as the season wears on. Regardless, his prospects against the Seahawks 5th ranked rush defense does not bode well for a big day.

Peterson (ankle) did not practice Friday, but is listed as probable against Seattle. "He'll be ready to go on Sunday," head coach Leslie Frazier told the Minneapolis Star Tribune. "We just wanted to give him a little rest prior to the game."

Analysis: It's a little uncommon to see Peterson get Friday as a day of rest from practice, but his sore ankle hasn't been an issue the past few weeks during games even though he's been limited at times in practice.

Peterson (ankle) was not practicing Friday during the portion open to the media, the Pioneer Press reports.

Analysis: Peterson was limited in practice Wednesday and Thursday, and it's possible that the Vikings plan to have him practice during the closed portion. We should know more following practice, but his absence is slightly concerning. Consider him questionable until we know more.

Harvin, Peterson limited in practice

Minnesota Vikings running back Adrian Peterson (ankle) and wide receiver Percy Harvin (hamstring) were limited in practice, but the team is only resting its two best players. Expect them both to take the field Sunday against the Seattle Seahawks. FULL INJURY ROUNDUP

Analysis: Temper expectations against a Seattle defense which ranks 5th against the run and 15th versus the pass. That said, each player is too explosive to sit regardless of the matchup.

Peterson (ankle) was limited for the second consecutive day at practice Thursday, 1500espn.com reports.

Analysis: There's been nothing to suggest that Peterson's Week 9 status is in any peril. Look for the Vikings to list him as probable for Sunday's game against the Seahawks come Friday.

Peterson (ankle) was a limited participant in Wednesday's practice, the team's official web site reports.

Analysis: Peterson has missed or been limited in practice the past few weeks with a sore ankle, but it hasn't hindered him during games. That shouldn't change this week against Seattle.

Peterson reclaims elite status

In his "Move the Sticks" report, NFL.com's Daniel Jeremiah notes Adrian Peterson "has racked up a league-leading 775 rushing yards in the Minnesota Vikings' first eight games. He's running with his trademark combination of explosiveness and power and continues to improve each and every week." READ: WEEK 8 NOTES

Analysis: AD has churned his way to second among all fantasy running backs with 113 points this season. He'll face a true test this week against a Seahawks rush defense which has allowed just 3 scores all season.

Peterson (ankle) had 15 carries for 123 yards, including a 64-yard touchdown, in Thursday's loss to Tampa Bay. However, he did lose a key fumble in the second quarter.

Analysis: Peterson finally broke a long run, but his stats could have been even better if the Vikings hadn't fallen behind early. Peterson didn't have a carry in the fourth quarter amid a blowout loss. Still, Peterson continues to look like the dominant running player he was before his knee surgery.

Peterson (ankle) is listed as active for Thursday's game against Tampa Bay.

Analysis: Peterson is averaging 93.1 rushing yards per game and K.C.'s Jamaal Charles is logging yards at a 98.5 clip, both top-five marks in the NFL, which is a remarkable stat given that both players are coming off torn ACL's.

Peterson to face stacked front on TNF

In his Thursday Night Football analysis, Bucky Brooks expects Peterson to see "more eight-man fronts from the Buccaneers; I wouldn't be surprised if Greg Schiano calls more run blitzes on early downs in an attempt to force the Vikings into long-yardage situations." FULL TNF ANALYSIS

Analysis: The Buccaneers are only allowing a NFL-best 3.1 yards per carry to opposing running backs. However, AP did explode for 120 yards and two scores against them last season. Start him as needed.

Peterson (ankle) is listed as probable for Thursday's game against Tampa Bay, ESPN 1500 am Twin Cities reports.

Analysis: Peterson missed Minnesota's only full practice Tuesday on a short week to give his ankle a rest, but he's fully expected to start against Tampa Bay.

Adrian Peterson: (Knee) Misses Practice

Peterson (ankle) missed practice Tuesday, Judd Zulgad of 1500espn.com reports.

Analysis: Coach Leslie Frazier said Peterson would be limited in practice, so this is a change of plans. However, Peterson, who is coming off a season-high 153-yard rushing performance, is expected to be fine for Thursday night's game against the Buccaneers.

Peterson, Vikings continue to amaze

NFL.com's Michael Lombardi believes "It's remarkable that running back Adrian Peterson is back to his old form so soon after an anterior cruciate ligament injury, but it's even more remarkable that Minnesota beat the Arizona Cardinals with quarterback Christian Ponder throwing for just 58 yards." READ: FRONT OFFICE VIEW

Analysis: Peterson will be squaring off against the Buccaneers' 3rd ranked rushing defense in Week 8, but the unit has allowed five rushing scores on the season.

Head coach Leslie Frazier said Peterson (ankle) will be limited in practice, the Pioneer Press reports.

Analysis: Frazier said Peterson's ankle wasn't as sore after Sunday's game against Arizona as it was after Week 6, which is good news. Odds are Frazier wants to play it safe since the Vikings have a short week. Expect him to be in his usual role Thursday against Tampa Bay.

Peterson's ankle, which has been sore the past two weeks, didn't get worse in Sunday's win over Arizona. "He's a little sore, but not as sore as he was a week ago Monday. So, that's encouraging," head coach Leslie Frazier told ESPN 1500 am Twin Cities.

Analysis: Peterson missed two days of practice last week to give his ankle some rest, but it didn't appear to be an issue as he ran for 153 yards. He may need to rest it again this week in practice, but it doesn't look like a major worry.

Peterson (ankle) had 23 carries for 153 yards and a touchdown Sunday against the Cardinals. He also added six receiving yards on two catches.

Analysis: The Vikings rode Peterson on Sunday, giving him 23 carries while having quarterback Christian Ponder throw only 17 passes. The touchdown was Peterson's first since Week 1 and he rushed for over 100 yards for only the second time this year. He's got a tough matchup next week against a Bucs defense that was ranked fourth in the NFL against the run heading into Week 7.

AP scores early

Peterson started out the day with 48 yards rushing and a touchdown in the first quarter of the Vikings' matchup against the Cardinals. FOLLOW WITH GAME CENTER

Analysis: It's a great start against an Arizona defense which had only allowed three rushing TDs leading up to this game.

Peterson (ankle) will play Sunday against Arizona.

Analysis: Peterson sat out two practices during the week to rest his sore ankle. However, make sure he's in your lineup versus the Cardinals' 19th ranked run defense.

Battle of wills for Peterson

In his "Playbook" breakdown of the Cardinals vs. Vikings, NFL Network's Sterling Sharpe notes Peterson's success has been largely due to running the "lead-draw" play out of the "I-formation" this season. WATCH PLAYBOOK PREVIEW

Analysis: Peterson hasn't scored in five-straight games and the Cards' defense has not allowed a TD or more than 76 yards rushing in their two road games. Temper expectations for the veteran back this week.

Peterson (ankle) was a full participant in Friday's practice and is listed as probable this week against Arizona, the team's official web site reports.

Analysis: Peterson missed practice the past two days to give his sore ankle a rest, but he's expected to start Sunday.

Peterson sits out practice again

After sitting out Thursday's practice, Peterson stated "Since I twisted it up and it happened, it's been hurting consistently," Peterson said. "Then we go out and play (against the Washington Redskins), it re-aggravates it, just the cutting and different things you're doing out there. So, it's sore, but you've just got to push through it." FULL REPORT

Analysis: Given Peterson was able to return from a major knee injury in record time and produce as if he hasn't missed a step, fantasy owners shouldn't be too concerned about his ability to overcome a sprained ankle. Keeb tabs on his progress, but expect him to be out there for you.

Adrian Peterson: Resting Ankle Again Thursday

Peterson will not practice for a second consecutive day Thursday to rest for his sore ankle, the Minneapolis Star Tribune reports.

Analysis: Peterson is still expected to play this week and the move is being called precautionary. He also says he's taking time off since the Vikings have two games in five days with a Thursday game next week. Still, it's a little worrisome that he's missed two days of practice, so check to make sure he can practice Friday.

Peterson sits out practice

Minnesota Vikings running back Adrian Peterson (ankle) sat out practice Wednesday. He's fully expected to play this week against the Arizona Cardinals, but the lingering issue is a bit of a concern. FULL INJURY ROUNDUP

Analysis: Given how well he's been playing, it's easy to forget this is a guy who is coming of a major injury. He'll be ready for use on Sunday, but this could be the normal routine during the week.

Peterson (ankle) will not practice Wednesday to give him rest for his sore ankle, but he's expected to play this week, the St. Paul Pioneer Press reports.

Analysis: Peterson missed a day of practice last week to give his ankle a rest, but it didn't appear to be a problem during Sunday's game. This injury looks minor, but watch to make sure he returns to practice later this week.

Peterson (ankle) had 17 carries for 79 yards and seven catches for 50 yards Sunday against the Redskins.

Analysis: Peterson has gotten over 100 total yards in four straight games, although fantasy owners have to be a tad bit disappointed that he hasn't gotten into the end zone since Week 1. That could very well change next week against the Cardinals, who gave up 165 rushing yards and two rushing touchdowns to the Bills in Week 6.

Peterson (ankle) will play Sunday in Washington.

Analysis: Peterson will take the field after he was limited much of the week in practice due to a sore ankle. Feel free to use him as you normally would.

Peterson (ankle) was a full participant in Friday's practice and is listed as probable against Washington, the team's official web site reports.

Analysis: Both Peterson and head coach Leslie Frazier said they expect Peterson to play and his ankle injury appears minor. He was limited earlier in the week, but was able to fully practice Friday.

Vikings boast two "Jordans"

Adrian Peterson says he and Percy Harvin are the best two players in the NFL, stating "there are two Jordans on this team. I'm not trying to be cocky. I'm just very confident in my abilities." FULL STATEMENTS

Analysis: Fantasy expert Jason Smith agrees, noting in his Higher/Lower column that Harvin is "on par with Adrian Peterson. He's averaging over seven catches per game to go along with two- to -three rushing attempts per week, which nets you an extra couple of points as well. He's got a phenomenal matchup this week against the Washington Redskins, who rank 31st overall in passing yards allowed.

Peterson (ankle) was a limited participant in Thursday's practice, ESPN 1500 am Twin Cities reports.

Analysis: Peterson didn't practice Wednesday, but it was more of a day off and he says he'll be able to play this week. Still, check to make sure he's able to practice Friday.

Peterson (ankle) said that there's no doubt in his mind that he'll be ready to play Sunday against the Redskins, 1500espn.com reports.

Analysis: Peterson has been undergoing treatment due to some soreness in his ankle, but he's eager to take the field Sunday against the Redskins, especially since that's the team he was facing back on December 24, 2011 when he tore his ACL.

Peterson misses practice

Minnesota Vikings running back Adrian Peterson (ankle) was held out of Wednesday's practice, but coach Leslie Frazier has already said he'll be good to go against the Washington Redskins. FULL WEEK 6 INJURY ROUNDUP

Analysis: Temper expectations on Peterson this week against a Washington defense which is allowing an average of just 87.8 yards per game.

Peterson (ankle) will not practice Wednesday, ESPN 1500 am Twin Cities reports.

Analysis: Peterson said he played through a minor ankle injury in Sunday's game, so this is likely just a day of rest. We'd expect him to play this week, but watch to make sure he returns to practice later in the week.

Peterson injured one of his ankles on his first carry early in Sunday's win over Tennessee, but was able to play a full game. "The whole game I was fighting through it," Peterson told ESPN 1500 am Twin Cities. "The wrong tackle aggravates it, but I got through it."

Analysis: Peterson still gained 88 yards on 17 carries despite the ailment, so it must be minor. Still, check to see if becomes an issue in practice this week.

Peterson had 88 rushing yards on 17 carries and three catches for 15 yards Sunday against the Titans.

Analysis: Peterson has eclipsed 100 total yards in three straight games, although he's failed to get into the end zone since Week 1. The Vikings could be passing a lot next week against the weak Redskins' secondary, although Peterson should still get plenty of touches.

Knee not an issue for A.P.

Adrian Peterson: My knee is better than it was a year ago. FULL STORY

Analysis: In his Week 5 Like/Dislike report, fantasy expert Adam Rank believes Adrian Peterson will have a rushing touchdown against the Titans this week. Peterson has plenty of upside this week, but temper expectations, as he has yet to score more than 12.20 fantasy points since his 20 point Week 1 performance.

Peterson returning to form

Adrian Peterson again looks like the "Adrian of old" rather than an old Adrian. FULL STORY

Analysis: Peterson has proven he belongs in starting lineups, but he is most trustworthy as a No. 2 RB given his current numbers.

Peterson had 21 carries for 102 yards and four catches for 20 yards Sunday against the Lions.

Analysis: Peterson eclipsed 100 rushing yards for the first time since October 23 of last year, although he's now gone three straight games without a touchdown. He faces a tough Titans' run defense next week that just held the Texans to 95 rushing yards.

Peterson proving consistent

Vikings RB Adrian Peterson was unable to reach the end zone in Week 4 action, but he did total 122 yards in the Vikings win over the Detroit Lions.

Analysis: Peterson has been a reliable No. 2 fantasy RB, but he has not scored more than 13 fantasy points since Week 1.

Adrian Peterson: (Knee) Nearing 100 Percent

Peterson admitted that his knee is not quite 100 percent but thinks it's close, the Pioneer Press reports.

Analysis: "When I look in the mirror, I'm like, 'OK, my right leg is obviously bigger than my left,'" Peterson said. "I know it's not as strong as far as different things that I do. That's when I'll be able to tell, when I won't be able to tell the difference between the strength of both legs." Peterson continues to inch closer to being fully back from his knee injury and is looking to increase his workload going forward. "I feel like the rust is knocked off now," Peterson said. "That's what I needed, and I'll be ready to roll even better."

Peterson didn't have any carries in the final five minutes of Sunday's win over the 49ers as the Vikings wanted to reduce his workload. "We looked at the number of carries (Peterson had) and we wanted to preserve him a little bit," head coach Leslie Frazier told ESPN 1500 am Twin Cities.

Analysis: Peterson gained 86 yards on 25 carries, but Toby Gerhart had the team's final eight carries. It's probably not a huge cause for concern for Peterson's fantasy value as the Vikings had an 11-point lead at the time, but it shows the Vikings are still mindful of his workload given his return from a torn ACL in his knee just nine months ago.

Peterson had 25 carries for 86 yards and two catches for 21 yards Sunday against the 49ers.

Analysis: 107 total yards against the 49ers' defense is a very solid contribution from any running back and especially one who is less than a year removed from knee surgery. The 3.4 YPC wasn't great and fantasy owners were probably disappointed with the lack of a score, but Peterson continues to impress with his performances this year.

A.P. to carry heavier load

Leslie Frazier says Adrian Peterson is ready for more carries.

Analysis: Peterson tailed off last week after a solid Week 1 performance, so the extra workload only bolsters his value. Still, he's safest used as a No. 2 RB until he is back to the AP we're used to.

Peterson (knee) fully participated in Wednesday's practice and isn't even listed on the team's official injury report.

Analysis: He was listed last week even after playing in Week 1, so this is another sign the team isn't worried about his knee. The Vikings may not even have a limit on his carries this week.

Peterson (knee) had 16 carries for 60 yards and three catches for 20 yards during Sunday's loss to the Colts.

Analysis: Peterson grabbed 16 of 23 carries (not including Christian Ponder's three) out of the Vikings' backfield and appears to have it back to himself. Fantasy owners are hoping for a few more touches from Peterson, although the coaching staff seems to be comfortable with his 15-20 right now. He faces a very tough game next week against the 49ers' defense.

Key Actives - Peterson, Cruz, Foster and Richardson

Peterson, Cruz, Foster and Richardson are all active as expected. Get all of the latest inactive news on NFL.com.

Analysis: This is good news for fantasy owners. Get these key players in your Week 2 lineup.

Adrian Peterson: (Knee) Active Sunday

Peterson (knee) is active for Sunday's game at Indianapolis, the Minneapolis Star Tribune reports.

Analysis: After practicing fully the entire week, Peterson is set to take on a full workload - likely the 20-to-25 carries we're used to seeing from him.

Adrian Peterson: (Knee) Full Practice Friday

Peterson (knee) fully practiced Friday and is listed as probable this week against Indianapolis, the team's official web site reports.

Analysis: Peterson fully practiced all week, so he'll start Sunday. The Vikings have talked of limiting his workload to 20-25 carries this week, but that's along the lines of how was used before his knee injury in most games.

Peterson eyes record books

Adrian Peterson has his sights set on Emmitt Smith's all time rushing record and believes if he stays healhty it's something that "will come with time."

Analysis: There's no reason to doubt AP after watching his performance Week 1. Consider him a weekly must-start if he's on your roster.

Peterson (knee) was a full participant in Thursday's practice. He said he felt some soreness in his knee and tightness in patella on Sunday, but it was minor and he feels he's 95 percent of what he was before, ESPN 1500 am Twin Cities reports.

Analysis: Peterson said Monday that he didn't experience any soreness or swelling in his surgically-repaired knee, so this admission of some discomfort is a new wrinkle. Still, he's practiced at full speed so far this week and any soreness appears minor. The Vikings have talked of limiting his workload to 20-25 carries, but that's along the lines of how was used before the injury in most games.

Adrian Peterson: No Setbacks With Knee

Peterson (knee) was a full participant in Wednesday's practice, according to the ESPN 1500 am Twin Cites.

Analysis: Peterson didn't report any swelling or soreness in his knee on Monday after last week's game, so this is another good sign. The Vikings plan to increase his workload this week slightly, with head coach Leslie Frazier saying they'll try to limit him to 20-25 carries.

Adrian Peterson: No Soreness or Swelling in Knee After Game

Peterson said Monday he did not experience any soreness or swelling in his surgically-repaired knee after Sunday's game, the St. Paul Pioneer Press reports. Head coach Leslie Frazier said the team would try to limit his workload this week to 20-25 carries.

Analysis: Peterson had a remarkable return from a torn left ACL and MCL as he scored two touchdowns and had 17 carries just less than nine months removed from the injury. However, he's not out of the woods yet as we'll need to see how his knee responds to his first game action. So far, so good, but we'll need to see how it holds up the next week.

Peterson doesn't miss a beat

Vikings RB Adrian Peterson continued his freakish return from injury, racking up 84 yards and two touchdowns in his first live game action since surgery.

Analysis: Fantasy owners who took the risk and started him were rewarded with 20.70 fantasy points. Consider him back to normal from here on out.

Peterson (knee) had 17 carries for 84 yards and two touchdowns during Sunday's win over the Jaguars.

Analysis: Peterson also added one catch for three yards in a performance that was much greater than most projected. His 17 carries were on the higher-end of expectations, but the two touchdowns were certainly more surprising. His workload probably won't increase by a large degree, but it seems he will get the touches near the end-zone, keeping his fantasy value relatively high.

Adrian Peterson: (Knee) Active Sunday

Peterson (knee) is active for Sunday's game against the Jaguars and will start, the Vikings' official Twitter feed reports.

Analysis: Many reports in recent days have indicated that Peterson will see something in the vicinity of 10 plays this week, but that's hardly a lock as head coach Leslie Frazier hasn't tipped his hand regarding Peterson's role. As a result, Toby Gerhart should be significantly involved in the Minnesota offense and Peterson may belong on the bench for those who have suitable alternatives in Week 1.

Peterson (knee) will play Sunday, Jason Cole of Yahoo! Sports reports. However, he'll share carries with Toby Gerhart.

Analysis: We'll know if he's active for the game shortly, but this report adds to the growing sentiment that he will play Sunday, but with a limited role that most project to be 5 to 10 plays. He's a risky fantasy option this week as a result.

Adrian Peterson: 10-15 Carries Expected If Active Sunday

A team source says the team is aiming for Peterson to receive around 10 to 15 carries if he is ruled active for Sunday's game against the Jaguars, CBS Sports' Jason LaCanfora reports.

Analysis: Peterson's status for Week 1 will officially be determined Sunday morning, and he still might not necessarily start over Toby Gerhart if he's active. However, a range of 10 to 15 carries seems to indicate a roughly 50-50 split of carries with Gerhart, which would be a bit more than originally expected. The Vikings may ultimately opt for a more conservative approach with Peterson when it comes to the game, but if he's cleared to play, it appears that it won't simply be for just one series.

Peterson's (knee) status for Week 1 will be determined Sunday morning, the Minneapolis Star-Tribune reports.

Analysis: The morning decision should give fantasy owners plenty of time to weigh whether or not they want to insert Peterson in their lineup if he's indeed cleared for action. In any event, don't expect him to take the bulk of the snaps at running back for the Vikings.

Adrian Peterson: (Knee) Now Sunday Decision

Peterson (knee) is listed as questionable for Sunday's game against Jacksonville, ESPN 1500 am Twin Cities reports. A decision on his status will now be made Sunday, head coach Leslie Frazier told Associated Press reports.

Analysis: Peterson was limited in practice Friday for a third consecutive day. Frazier had said that the team would make a decision Friday or Saturday. However, now it sounds like they may see how Peterson is feeling in pre-game warmups. Either way, it sounds like Peterson may only get 5-10 snaps in any scenario as he's eased back into action, but the Vikings still haven't made anything official.

Adrian Peterson: Status Could be Clarified Saturday

Peterson (knee) was listed as a limited participant in Thursday's practice on the team's official injury report. Vikings offensive coordinator Bill Musgrave said there is "not too much doubt" Peterson will play this week, ESPN 1500 am Twin Cities reports. Head coach Leslie Frazier also said the Vikings would make a decision about Peterson playing by Saturday, Minneapolis Star Tribune reports.

Analysis: It looks like Vikings will announce Friday night or Saturday that he'll play, but his role is expected to be limited with Tom Pelissero, the Vikings beat reporter ESPN 1500 am Twin Cities, speculating he may only get five to ten carries. At least it looks like fantasy owners may have more information on Peterson's status before Sunday with the Vikings set to make some kind of announcement on his status.

Peterson getting closer to full return

Minnesota Vikings running back Adrian Peterson "saw heavier contact in Wednesday's practice," Tom Pelissero of ESPN Twin Cities reports.

Analysis: Peterson is inching closer towards being a full-go for fantasy owners in Week 1, but fantasy owners should wait until he is named the starter before trusting him as anything more than a No. 2 RB.

Adrian Peterson: (Knee) Limited Wednesday

Peterson (knee) was listed as a limited participant in Wednesday's practice on the team's official injury report.

Analysis: Head coach Leslie Frazier said before practice that Peterson would have no restrictions on getting hit in practice (other than shots to his legs), which is an encouraging step. We'll need to see how his surgically-repaired knee feels the day after his first full contact practice. There have been reports Peterson may get limited carries this week even if deemed healthy, but his outlook could quickly change after a few days of practice.

Adrian Peterson: (Knee) Set To Take Hits

Peterson (knee) will have no limitations on players hitting him in practice Wednesday, other than to avoid shots to his legs, head coach Leslie Frazier told ESPN 1500 am Twin Cities.

Analysis: We'll have to see how Peterson holds up after a few days of full practice before we're really able to evaluate how many carries he may get this week. There have been reports Peterson may get limited carries even if healthy, but his outlook could change after a few days of practice.

Peterson a game-time decision

Minnesota Vikings running back Adrian Peterson remains a game-time decision, but coach Leslie Frazier is not optomistic he will play Week 1.

Analysis: Peterson has done nearly everything necessary to be ready for action, so this could be a case of the coach keeping the Jaguars staff from knowing what to prepare for. Since he plays in the morning game, fantasy owners should keep a close eye on his status before kickoff. Toby Gerhart will be the play if Peterson is held out.

Adrian Peterson: (Knee) Limited Carries if Active Week 1

Peterson (knee) will receive limited carries if he's cleared to play Week 1 against the Jaguars, the National Football Post reports.

Analysis: Coach Leslie Frazier hasn't said whether or not Peterson will play in Sunday's opener, but if he does, it will come with limited exposure. Although Peterson has reiterated that he'll be ready for Week 1, the club is intent on ensuring he remains healthy eight months removed from reconstructive knee surgery. In any event, expect Toby Gerhart to get the bulk of the looks at running back in Week 1.

Adrian Peterson: (Knee) Decision Likely to Go to the Wire

Coach Leslie Frazier says that the Vikings "without question" will take a decision on Peterson's (knee) Week 1 status up to Sunday, 1500ESPN.com's Tom Pelissero reports.

Analysis: Overall, Peterson's recovery from knee surgery has gone well, but as the regular season opener fast approaches, his status out of the gate remains unclear. Even if he does end up being active Sunday, it's uncertain how many carries Peterson would be in line for. Those who picked up Peterson, possibly at a discounted rate, hopefully have a viable plan B to turn to early on while this situation plays out.

Adrian Peterson: (Knee) Game-Time Decisoin for Week 1

Vikings head coach Leslie Frazier says he expects Peterson (knee) to be a game-time decision for Week 1, the Minneapolis Star Tribune reports.

Analysis: We'll likely get more information on Peterson's status and Minnesota's plans next week during practice, but if not Peterson may be a difficult player to use in Week 1 for fantasy purposes. Frazier is likely playing it safe, but it's not clear how many carries Peterson will get even if active as there's a real danger he could be brought along slowly. Still, all signs this preseason indicate he's ready to be on the field for the regular season.

Adrian Peterson: (Knee) Takes Upper-Body Contact In Practice

Peterson (knee) was allowed upper-body contact during Monday's practice, the Minneapolis Star Tribune reports.

Analysis: Another sign of progress for Peterson, but we'll need to see how he holds up under full contact. However, that may not come until a regular season game. It looks like Peterson will be ready for Week 1 of the regular season, but it's not clear how big his workload will be.

Adrian Peterson: Set to Face Contact Next Week

Peterson (knee) will experience contact in practice next week, ESPN's Chris Mortensen reports.

Analysis: Peterson is on track to start Week 1, but Mortensen notes he'll likely receive a lighter workload this season as he works his way back from the ACL injury. Expect Toby Gerhart to get a healthy dose of carries of his own, especially early on in the season.

Adrian Peterson: Knee Not Swelling Up After Practice

Peterson has experienced no swelling in his surgically-repaired left knee the day after practices, the St. Paul Pioneer Press reports.

Analysis: Peterson won't play in the preseason, but this news points toward him being ready for the first week of the regular season. However, it remains to be seen what kind of workload he'll get early in the season.

Adrian Peterson: Not Expected to Play in Exhibtion Games

The Vikings plan to hold Peterson (knee) out of their final two preseason games, the Minneapolis Star-Tribune reports.

Analysis: Peterson -- who is bouncing back from a torn ACL and MCL -- would prefer to get some preseason action in, but the Vikings are operating here with the big picture in mind. That big picture includes Peterson hopefully being on the field for the the team's regular season opener Sept. 9 against Jacksonville. Of course, if that ends up happening, it seems likely that Peterson would be somewhat limited and/or on a snap count out of the gate.

Adrian Peterson: (Knee) Unlikely to Play Friday

The Vikings don't plan to play Peterson (knee) Friday against San Diego, ESPN's Adam Schefter reports.

Analysis: The report suggests that Peterson may try to convince the Vikings to let him play, but at this point it seems prudent to ease Peterson back into the mix, no matter how well his recovery/rehab has gone to date.

Adrian Peterson: Continues to Progress

Coach Leslie Frazier said that the Vikings will decide by Tuesday or Wednesday whether or not Peterson (knee) will play in Friday's preseason game against San Diego, the Associated Press reports.

Analysis: In the meantime, Peterson will continue to have his practice participation upped this week. While Peterson's progress as he rehabs from reconstructive knee surgery has been highly encouraging, assuming he is available to play in Week 1, it's fair to wonder how heavily he will be used out of the gate. Moreover, as well as things appear to be going, it would figure to take some time for Peterson to cut and run with his pre-injury authority and explosiveness.

Peterson's (knee) workload in practice will be increased incrementally each day this week, Jeremy Fowler of the St. Paul Pioneer Press reports.

Analysis: Peterson began practicing in pads Tuesday, and it seems he's ready to start taking on a heavier workload. However, it's unclear if he'll be deemed ready for game action by the time Friday's contest against the Chargers rolls around.

Although Peterson (knee) has returned to practice, head coach Leslie Frazier said it's still not clear Peterson will get the majority of carries at the start of the season, the Minneapolis Star Tribune reports. "There's nothing to say that he could," Frazier said. "But I don't know if there were many things that were said that at 7 1/2 months he would be prepared to do what he's doing now. You don't really want to put parameters on his rehabilitation, you want to just let it go and see where it takes us."

Analysis: Peterson returned to practice in pads Tuesday. The next step is we'll need to see if he can play in a preseason game (which may be Minnesota's third preseason game). Frazier's comments are a bit cryptic, but they show the real risk with Peterson this season may be that he'll have a reduced workload early in the season even if he's in the starting lineup Week 1.

Peterson (knee) will take a handful of snaps from the huddle Tuesday, the St. Paul Pioneer Press reports.

Analysis: It will be Peterson's first official practice since tearing his ACL nearly eight months ago. He won't be tackled, but the Vikings will monitor how he cuts and reacts on running plays. "We're looking for the normal Adrian to emerge over time -- not today," offensive coordinator Bill Musgrave said. "We know it's a process." Musgrave also left open the possibility Peterson could play in preseason weeks 3 and 4.

Adrian Peterson: Off the PUP List

Dan Wiederer of the Minneapolis Star Tribune suspects that Peterson's (knee) only preseason game action will come in the Vikings' third exhibition game, Aug. 24 against the Chargers.

Analysis: In any case, Peterson is officially off the PUP list, with coach Leslie Frazier saying that activating Peterson is "just a part of the process." Peterson, who, in Frazier's words, "has done everything he can do on the side," can't don pads at practice until Tuesday, per the NFL's CBA.

Adrian Peterson: (Knee) Returns to Practice

Peterson (knee) was working with the first-team offense during Sunday's practice, ESPN 1500 am Twin Cities reports.

Analysis: We assume this means he was activated from the PUP list. He'll probably be eased into action, but it's a good sign he's back at practice. It's not clear what timetable the Vikings have in mind for his return, but head coach Leslie Frazier has said he'd like Peterson to play in a preseason game.

Adrian Peterson: Could Practice as Soon as Sunday

Peterson (knee) could return to practice as early as Sunday, ESPN 1500 am Twin Cities reports. Head coach Leslie Frazier says Peterson remains on track to be ready for the start of the regular season. "There are no indications at this point that he wouldn't be. Everything that he's done, he's right on point," Frazier said.

Analysis: Peterson won't play in Minnesota's preseason opener on Friday. The report speculates that Peterson could return to practice next week and play in the team's third preseason game. While Frazier has said the Vikings would like to get Peterson into a preseason game, they haven't really tipped their hand on their plans for Peterson's return to action. The danger for fantasy owners is that Peterson may be added to the active roster in time for Week 1, but will have a reduced workload for a few games as he's eased back into action. However, it seems very unlikely at this point that he'll be put on the regular season PUP list (missing six games), barring a setback.

Adrian Peterson: (Knee) Remains on PUP List

Peterson (knee) will not be activated from the PUP list before Minnesota's first preseason game, the Minneapolis Star Tribune reports.

Analysis: This isn't a huge surprise as he won't play in the first game since he hasn't practiced yet. He could be activated from the PUP list next week, but it's still not clear what plan the Vikings have for Peterson this preseason. Head coach Leslie Frazier has left the door open he could play in preseason games, but it's not certain he'll play either. Peterson continues to do work away from the field and hasn't had any setbacks, so it remains difficult to judge if he'll be active for Week 1 or how much he'll play if he is on the active roster.

Peterson (knee) has resumed his rehab after dealing with an allergic reaction to seafood jambalaya that led to a trip to the hospital, the Associated Press reports.

Analysis: The allergic reaction led Peterson to experience shortness of breath and also caused his face to swell, but he was back at work Tuesday. Peterson remains on the Vikings' preseason PUP list, but he is anxious to to cleared to practice, with an eye toward possibly getting in some preseason work. "I definitely want to play a preseason game, and that's the only way to get back to normal," Peterson said. "Going out there and … cutting and dodging guys and playing football. Getting back out on the field. Hopefully I will get the opportunity to do that." In any case, being in uniform for the team's Sept. 9 opener remains Peterson's main -- and hopefully realistic -- goal. "I feel like I will be ready to play. There's still time," Peterson said.

Peterson (knee) went to the hospital Monday afternoon after having an allergic reaction to seafood, Dan Wiederer of the Minneapolis Star Tribune reports.

Analysis: According to head coach Leslie Frazier, Peterson is OK and is expected to resume his rehab activities Tuesday after returning to the dorms for rest late Monday afternoon.

Minnesota would prefer that Peterson (knee) gets some work in the preseason. "Now, will that happen? I don't know," head coach Leslie Frazier told ESPN 1500 am Twin Cities. "We'll see how he progresses. But ideally, you'd like to see him get some carries at some point in the preseason just for his benefit, where he can gain some confidence and get a feel for where he is and where he needs to be by the first game of the season."

Analysis: Peterson took handoffs and caught passes out of the backfield on the side Saturday, but isn't able to fully participate in practice while on the preseason PUP list. Perhaps having Peterson play in the preseason is wishful thinking, but if not it would seem to indicate the Vikings seriously think Peterson will be ready for Week 1.

Peterson lands on PUP list

Vikings running back Adrian Peterson was designated with the Active/PUP list tag to start training camp on Friday. He can be activated at any time, so it seems to be a cautionary approach for the team to ensure he gets to full health.

Analysis: Though the designation is sure to scare some fantasy owners away, Peterson's value should hold tight as a No. 2 RB in fantasy drafts. If he does return to form early in the season, he could prove to be one of the better values in 2012.

Adrian Peterson: (Knee) Begins Preseason on PUP List

Peterson (knee) was placed on the preseason active/PUP list, the Minneapolis Star Tribune reports.

Analysis: Peterson is coming back from a torn ACL and MCL in his left knee in December. Peterson appears ahead of schedule as he was running this spring, so this may just be a case of the team trying to hold him back a bit. Since Peterson can be activated from the preseason PUP list at any time, this doesn't necessarily change his outlook for his chances of playing Week 1. However, it may indicate the Vikings are going to be more cautious with his comeback than Peterson would like.

The Vikings reportedly plan to place Peterson (knee) on the active/physically unable to perform list before Friday's walkthrough, 1500espn.com reports.

Analysis: Players on the preseason active/PUP list can be activated at any time, so the larger concern, should Peterson in fact start training camp on the list, is obviously how sound his health is after he tore the ACL and MCL in his left knee back on Dec. 24, 2011. It remains the stated goal to have Peterson out there for Week 1, but as the preseason progresses, we should have a better idea of how realistic that goal actually is.

Peterson (knee) will be evaluated today, and the Vikings will decide whether or not to place him on the active/PUP list, the St. Paul Pioneer Press reports.

Analysis: The expectation is that Minnesota will put Peterson on the PUP list for now since there isn't much to lose and he can return at any time. This gives the Vikings the flexibility to place Peterson on the regular season PUP- which would keep him out through at least the first six games- if he suffers a setback in his recovery from a torn ACL.

Peterson (knee) appeared in a Houston courtroom Friday morning, and his case was reset for Aug. 6 as he faces a misdemeanor charge of resisting arrest, the Star Tribune reports.

Analysis: Peterson's hearing on Friday was mainly procedural. The Vikings' star running back was arrested Saturday after an altercation with club security, but Peterson's attorney, Rusty Hardin, says at least four witnesses not affiliated with his client say Peterson was not causing trouble. Peterson's rehabilitation from a torn ACL is of more concern to fantasy owners, but we'll keep you updated on this case as well.

Peterson (knee) saw a doctor Tuesday for injuries suffered during his arrest, Kevin Seifert of ESPN.com reports.

Analysis: Peterson's attorney, Rusty Hardin, said his client suffered some facial abrasions during his arrest in Houston on Saturday. Peterson was charged with resisting arrest, but it seems he suffered very minor injuries in his scuffle with police.

The police report for Peterson's arrest states that Peterson shoved an off-duty police officer in the back after the officer told Peterson to leave a night club, the Associated Press reports.

Analysis: The report then claims that Peterson began yelling and resisted arrest as three officers attempted to subdue him. If he really did shove a police officer and then physically resist arrest, then it's exceptionally odd that police are merely going for a resisting arrest charge. Peterson is in any case unlikely to see noteworthy punishment if the resisting arrest charge remains the only charge, though if the police report is true, Peterson could certainly see an additional charge.

Adrian Peterson: Arrested Saturday Morning

Peterson was arrested for resisting arrest in Houston on Saturday morning, Houston Chronicle writer Jerome Solomon reports.

Analysis: Without additional charges, there will likely be nothing to see here, but we'll be on the lookout for more information.

Peterson's (knee) main focus remains gaining strength in his left leg, the St. Paul Pioneer Press reports.

Analysis: Peterson has been able to cut and run but believes the real test will come when he eventually begins practicing. "We need to see him cut and be able to explode out of a cut without any residual effects before determining maybe he can put the pads on," coach Leslie Frazier said.

Peterson targeting Week 1

Adrian Peterson believes "it's realistic" he will be ready for the start of the regular season. Though the news is hopeful, the true test will come when he takes reps in live action.

Analysis: Peterson has made amazing strides, but until he shows it on the field, it's safest to select him as a No. 2 RB in fantasy drafts.

Peterson (knee) thinks his goal of a Week 1 return is "realistic," NFL.com reports.

Analysis: "As of now, I feel like I'm heading in the right direction to meet that," Peterson said regarding his timetable for a Week 1 return from a torn ACL, suffered on Dec. 24. Peterson says he's been working out with "a different sense of urgency" and the past six weeks were "probably the hardest [he's] worked in [his] life."

Adrian Peterson: Optimism Regarding Week 1 Status

According to coach Leslie Frazier, Peterson is on pace in his recovery from knee surgery and there is some optimism that the team's star running back back could play in Week 1, ESPN's Tom Pelissero reports.

Analysis: Frazier added that he's not sure about Peterson's training camp status as of now, but the positive reports regarding the running back's rehab continue to trickle in.

Simpson suspended first three games

Minnesota Vikings wide receiver Jerome Simpson was officially suspended for the first three games of the NFL season. The suspension was expected as a result of his violation of the league's substance abuse policy.

Analysis: With Simpson sitting out the first three games and Adrian Peterson's status in question for week one, the biggest benefactor is Percy Harvin. The receiver could get touches out of the backfield and will be the top target for quarterback Christian Ponder. Simpson is still a player to target in fantasy drafts as a No. 3 or 4 wide receiver.

Adrian Peterson: (Knee) Remains Optimistic

Peterson (knee) believes that he could ready to participate in a limited capacity when the Vikings open training camp on July 27, 1500espn.com reports. "I imagine myself definitely getting stronger and doing a lot on the side," said Peterson. "And I also imagine myself being able to get out there and be involved, too. That's my imagination...I feel like I'll be able to do something."

Analysis: That said, the report notes that Peterson will almost certainly be placed on the training camp/PUP list while he continues to rehab his knee. For his part, coach Leslie Frazier notes, "it's early right now. But in my mind right now, it'd be better to be doing things on the side (in camp) until we know and feel comfortable that he can get out there and interact with the players." In any case, while Peterson's recovery is going well and his optimism is a positive sign, his potential Week 1 availability remains uncertain, with his progress toward that goal being one of the main story lines to follow once NFL training camps get going.

Peterson (ACL, MCL surgeries) believes he is "50-50" on being ready for training camp, Josina Anderson of ESPN.com reports.

Analysis: Peterson believes he could participate in practice and go through drills, but he is "going to follow the protocol."

Vikings trainer Eric Sugarman isn't ready to say Peterson (knee) will be ready for the start of the regular season even though Peterson's been running in recent weeks."He'll keep throwing that out there. And good for him," Sugarman told the Minneapolis Star Tribune. "That's great. That's obviously our goal, to get him playing the first game. But only if he's functionally safe to do it. This is our franchise. We can't be foolish about this."

Analysis: Sugarman said Peterson's left quadriceps is back to about 80 percent strength, has no swelling in his left leg and his leg has regained normal motion. However, Peterson has problems with deceleration, which is normal in a recovery from an ACL tear. Peterson has been running since late March and has started to cut. He's ahead of schedule, but it's still too early to say he'll be ready for Week 1 - and Sugarman's comments also may indicate the Vikings may play it safe since the team may not be as worried about 2012 than 2013.

Adrian Peterson: Not a Lock for Week 1

Though Peterson (knee) hopes to be back in action by Week 1 this coming season, Vikings head athletic trainer Eric Sugarman suggests that's no lock to occur, the Minneapolis Star-Tribune reports. "I love Adrian," Sugarman said Tuesday. "But let's make this clear: I'm still not going to be quoted as saying he's going to play in the first game. That's not fair. I don't know that."

Analysis: "He'll keep throwing that out there. And good for him," Sugarman added. "That's great. That's obviously our goal, to get him playing the first game. But only if he's functionally safe to do it. This is our franchise. We can't be foolish about this." Sugarman said Peterson's left quadriceps is back to about 80 percent strength, has no swelling in his left leg and his leg has regained normal motion. However, Peterson has problems with deceleration, which is normal in a recovery from an ACL tear. Peterson has been running since late March and has started to cut. Peterson and Sugarman are slated to hold a news conference Wednesday to update the running back's progress in his rehab, but from all accounts that has been going well. In any case, Peterson's status will be worth monitoring closely in the coming weeks, as when to draft him this season is very much up for debate at this point.

Adrian Peterson: (Knee) Making Progress

Peterson (knee) ran with teammates this week and made cuts, head coach Leslie Frazier told Minneapolis Star Tribune reports.

Analysis: Peterson is coming back from a torn ACL in his left knee. He reportedly beat several teammates in wind sprints. It sounds like he's making progress faster than expected, but it's still too early to judge whether he'll be ready for the first week of the regular season.

Adrian Peterson: (Knee) Gets Some Running In

Peterson ran without complications last week for the first time since surgery to repair a torn ACL in his left knee. "Our trainer, Eric Sugarman, was really impressed with his movement and the things he was able to do. He's on schedule. He's doing well," head coach Leslie Frazier told the St. Paul Pioneer Press.

Analysis: Peterson's recovery so far is going well without any setbacks. He's said his goal is to be ready by Week 1, but it's still too early in his recovery to estimate when he'll be able to play.

Adrian Peterson: (Knee) Ahead of Schedule in Recovery

Peterson, who underwent reconstructive knee surgery on Dec. 30, says that he is ahead of schedule in his recovery, the Tucson Citizen reports. "Right now my goal is to be back by ... the regular-season opener," Peterson said Tuesday. "That's my goal."

Analysis: That's a good goal, but how realistic that is remains to be seen, something which Peterson acknowledges. "Ultimately, I've got to make sure I am 100 percent before I get back out there," Peterson said. "It's going good so far." In any case, while there are still huge questions surrounding the running back's status, it is nonetheless encouraging that things are going well for him at this stage and given his reputation as a quick healer, he certainly can't be ruled out for Week 1. Perhaps the larger issue regarding his 2012 fantasy value lies in what, if anything, Peterson might lose in terms of power and burst upon his return, at least out of the gate.

Adrian Peterson: (Knee) Placed on IR

The Vikings have placed Peterson (knee) on IR, ESPN's Adam Schefter reports.

Analysis: To add some needed running back depth in the wake of Peterson's torn ACL/MCL, the Vikings signed Caleb King on Monday to back up Toby Gerhart.

Adrian Peterson: Surgery on Tap in 7-10 Days

Vikings head athletic trainer, Eric Sugarman, said that Peterson, who sustained a torn ACL and MCL on Saturday, will undergo surgery in 7-10 days, Chip Scoggins of the Minneapolis Star Tribune reports.

Analysis: Recovery time for the sort of surgery Peterson has on tap is typically 8-9 months. Sugarman added the goal is for Peterson -- who he says "has the DNA to heal fast" -- to be ready by the Vikings' first game in 2012. That's not a scenario that we'd rule out, as there are players we have seen who have met that sort of timetable, but perhaps a bigger concern is what, if anything, Peterson stands to lose in terms of power and burst (initially, at least) upon his return.

Adrian Peterson: Vikings Confirm ACL Tear

The Vikings confirmed Peterson's torn left ACL in an official statement.

Analysis: Coach Leslie Frazier will give a further update at his Monday press conference, but it is believed that Peterson suffered a torn MCL as well. Assuming there is MCL damage, Peterson's surgery is likely still a couple of weeks away. Either way, a long recovery period lies ahead for Peterson, one which clouds his availability to start the 2012 season on time. Moreover, once Peterson does return, it's fair to wonder how much his speed and explosiveness will be impacted by the injury, especially out of the gate. Toby Gerhart will head the Vikings' backfield in the team's season finale, but beyond that, Peterson's uncertain status will likely force the Vikings to address the running back position, either through the draft, free agency or a trade.

Adrian Peterson: Torn ACL Confirmed

An MRI revealed that Peterson tore the ACL in his left knee Saturday against the Redskins, ESPN.com reports.

Analysis: In addition, Peterson also reportedly tore his MCL. Given the severity and timing of the injury, Peterson's availability to start the 2012 season is in doubt. In the short-term, Toby Gerhart will fill in for Peterson in Week 17, but this is obviously a devastating blow for a Vikings team already in the midst of an awful season.

Adrian Peterson: Report Says Likely Torn ACL

Peterson likely tore the anterior cruciate ligament in his left knee and suffered additional structural damage during Sunday's win over Washington, Jason Cole of Yahoo! Sports reports. A team source indicated Peterson appeared to have a torn ACL from an on-field test after the injury.

Analysis: Head coach Leslie Frazier called Peterson's injury a sprain after the game, but other reports indicate the injury is much more serious. We'll need to wait for further tests before we know for sure about Peterson's knee, but he'll be out next week and this could impact his fantasy value for 2012.

Adrian Peterson: Sprained Knee

Coach Leslie Frazier is calling Peterson's knee injury a sprain, ESPN's John Clayton reports.

Analysis: Though a knee sprain is probably enough to keep Peterson out of the Vikings' season finale, if the report is accurate, it would actually represent good news, given the more serious possibilities.

Adrian Peterson: Apparent Left Knee Injury

Peterson had to be helped off the field Saturday with what appeared to be a really nasty knee injury.

Analysis: Peterson could not put any weight on his left leg after he got bent back awkwardly, so the it looks like the Vikings will probably turn to Toby Gerhart for the rest of the afternoon.

Adrian Peterson: Not on Injury Report

Peterson (ankle) does not appear on Wednesday's injury report.

Analysis: Peterson didn't get too much work in last week's loss to the Saints, but he figures to be more involved against the Redskins on Saturday.

Peterson (ankle) had 10 carries for 60 yards in Sunday's loss to the Saints.

Analysis: Peterson had a nice 39-yard scamper, but was held in check otherwise. He may have received more work in the second half if not for the fact that the Saints pulled away with two quick touchdowns in the third quarter.

Adrian Peterson: Active; Starting Sunday

Peterson (ankle) is active and will start Sunday against the Saints, the Vikings' official Twitter feed reports.

Analysis: He's been chomping at the bit to get back in the lineup for a couple of weeks, but the Vikings have taken a cautious approach in his recovery from a high ankle sprain and are seemingly willing to turn him loose in Week 15.

Adrian Peterson: (Ankle) Full Practice Friday

Peterson (ankle) was a full participant in Friday's practice and is listed as probable against the Saints. However, he may not get a full workload. "Well, he's missed some time, so we'll have to kind of work him in there," head coach Leslie Frazier told the ESPN 1500 am Twin Cities. "It wouldn't be as if he had not missed a game. So, we'll have to monitor how he's doing."

Analysis: It sounds like the Vikings will see how Peterson's ankle holds up and give Toby Gerhart more carries that he usually gets as a backup. However, Peterson should start and still get enough of a workload that he'll be worth starting in most fantasy leagues.

Adrian Peterson: Tells Fantasy Owners He'll Play

In an interview with ESPN, Peterson (ankle) said that he will play Sunday against the Saints.

Analysis: While acknowledging that his ankle is probably at about 85 percent, Peterson took the time to assure his concerned fantasy owners that he would be out there this weekend. As long as Peterson is able to avoid any in-game setbacks Sunday, he should be able to produce just fine in his return to action this week.

Peterson (ankle) was listed as being limited in practice Thursday, but offensive coordinator Bill Musgrave said Peterson was cutting better and is confident he'll play Sunday, ESPN 1500 am Twin Cities reports.

Analysis: All signs point to Peterson starting this week unless he has a setback Friday.

Adrian Peterson: (Ankle) On Track to Return This Week

Peterson (ankle) was limited in practice Wednesday, but is on track to start this week, head coach Leslie Frazier told ESPN 1500 am Twin Cities.

Analysis: We'll have to see how Peterson holds up after a week of practice, but all indications so far are that he went through Wednesday's session fine and should play this week.

Adrian Peterson: (Ankle) Back on the Field Wednesday

Peterson (ankle) is practicing Wednesday, ESPN 1500 am Twin Cities reports.

Analysis: Coach Leslie Frazier indicated Monday that Peterson should be back this week. However, we'll need to see how he holds up in practice during the week.

Adrian Peterson: Week 15 Return on Tap?

Coach Leslie Frazier indicated Monday that Peterson (ankle) should be back this week, according to 1500ESPN.com's Tom Pelissero.

Analysis: Frazier noted that Peterson was very close to playing Sunday, which suggests that the running back's chances to suit up this weekend against the Saints are quite plausible, barring a setback.

Adrian Peterson: Officially Inactive

Peterson (ankle) is officially inactive Sunday, Adam Schefter of ESPN reports.

Analysis: Peterson was limited in practice the entire week and clearly didn't appear to be at full strength. The Vikings have no reason to play him with a chance to aggravate the injury at this point in the season. Toby Gerhart is in line for another start this week.

Adrian Peterson: (Ankle) Will Not Play Against Detroit

Peterson (ankle) will not play Sunday against Detroit, NFL Network's Jason La Canfora reports.

Analysis: He traveled with the team after practicing on a limited basis last week. It sounds like the Vikings will hold him out another week, but wait for the inactive list for official confirmation.

Peterson (ankle) is listed as questionable for Sunday's game at Detroit. Peterson says he's about 80 percent healthy, ESPN 1500 am Twin Cities reports.

Analysis: Peterson will likely be a game-time decision, but head coach Leslier Frazier curiously said the team will make a decision before Sunday - which may suggest he won't play. While it's encouraging that Peterson returned to practice this week, the Vikings may not be motivated to have him return if not a full strength in a meaningless game.

Peterson (ankle) was on the field, but not doing much during group drills Friday, according to 1500ESPN.com's Tom Pelissero.

Analysis: Pelissero goes on to say that Peterson's Week 14 status is still up in the air, so this could evolve into a game-time decision for Sunday's 1:00 ET kickoff against the Lions.

Adrian Peterson: Back In Practice Thursday

Coach Leslie Frazier said that Peterson (ankle) did not experience any pain when planting and cutting at Thursday's practice, Judd Zulgad of 1500ESPN.com reports.

Analysis: That sounds promising, but Frazier also noted that the Vikings' trainers wants to see how the running back feels Friday morning after Thursday's work.

Adrian Peterson: (Ankle) Returns to Practice

Peterson (ankle) returned to practice Thursday, St. Paul Pioneer Press reports.

Analysis: We'll need to see how much he's able to participate and if he's able to practice two days in a row, but the odds have increased significantly that he'll be able to play this week.

Adrian Peterson: (Ankle) Will Try Practicing Thursday

Peterson (ankle) will not practice Wednesday, but will attempt to practice Thursday, ESPN 1500 am Twin Cities reports.

Analysis: Peterson said Tuesday that he's about 70 percent recovered from his high ankle sprain, so it sounds like there's a decent chance he'll play this week. However, we'll need to see him get on the practice field and see how his ankle holds before he can be considered for fantasy lineups.

Adrian Peterson: Says He's 70 Percent

Peterson says he is about "70 percent" recovered from his high ankle sprain, the Star Tribune reports.

Analysis: This is contrary to head coach Leslie Frazier's announcement that Peterson is "very close" to returning, unless Frazier is planning on putting his best player on the field at less than 100 percent with nothing play for.

Peterson (ankle) is "very close" to returning, head coach Leslie Frazier announced in his Monday press conference, the St. Paul Pioneer Press reports.

Analysis: It was a good sign that Peterson was able to do some running last week, which could indicate he's ahead of schedule in his return from a high ankle sprain. However, other reports have said he may be out a few more weeks and the Vikings won't rush him back. Either way, we'll know more when we see if he can practice this week beginning Wednesday.

Adrian Peterson: Not Ready to Play

Peterson (ankle) has been ruled out for Sunday's game against the Broncos, Jeremy Fowler of the Pioneer Press reports.

Analysis: Peterson has apparently been making some progress with his ankle, but at 2-9, rushing him back makes no sense for the Vikings. As a result, Toby Gerhart is in line for another start at running back for Minnesota on Sunday.

Adrian Peterson: (Ankle) Not Practicing Thursday

Peterson won't practice Thursday, but is running and says that he's "getting more movement" with his ankle, Jeremy Fowler of the Pioneer Press reports.

Analysis: Peterson expects a decision on his status for Sunday's game against the Broncos to be made Saturday, but at 2-9, we'd assume that the Vikings won't unnecessarily push his return.

Peterson (high ankle sprain) will work on the side with athletic trainers Wednesday, and there's a chance he could participate in at least a limited portion of practice on Thursday, ESPN 1500 am Twin Cities reports. Head coach Leslie Frazier hasn't ruled him out for Sunday's game against Denver.

Analysis: It sounds like Peterson is making progress, but it still seems like a long shot he'll return this week. Still, watch to see if he's able to participate in some portion of practice at any point this week.

Peterson (high ankle sprain) continues to make progress, but his Week 13 status remains up in the air, 1500espn.com reports.

Analysis: "He is improving so that's encouraging for us," coach Leslie Frazier said Monday. It's too early in the week to get a good grip on Peterson's chances of playing Sunday against the Broncos, but we suspect this could evolve into a game-time decision favoring Peterson sitting out another game.

Adrian Peterson: Officially Out Sunday

Peterson (high ankle sprain) has been declared out for Sunday's game against Atlanta, ESPN.com reports.

Analysis: As expected, Toby Gerhart will start for the Vikings on Sunday.

According to head coach Leslie Frazier, Peterson (high ankle sprain) is "very, very doubtful" for Sunday's game against Atlanta, the Saint Paul Pioneer Press reports.

Analysis: It sounds like Peterson's availability for Week 13 is far from guaranteed at this point, as well. Toby Gerhart is likely to start in Peteron's place against the Falcons.

Adrian Peterson: (Ankle) Will be Listed as Doubtful

According to coach Leslie Frazier, Peterson (ankle) will be listed as doubtful for Sunday's game against the Falcons, the Vikings' official site reports.

Analysis: We've seen exceptions here and there, but the doubtful designation leads to inactive status in most cases. Look for Toby Gerhart to get the start at running back for the Vikings on Sunday, with Lorenzo Booker and receiver Percy Harvin in the mix for carries to a lesser extent.

Adrian Peterson: (Ankle) Misses Another Practice

Peterson missed his third consecutive practice Friday because of a high left ankle sprain that suffered last Sunday, 1500espn.com reports.

Analysis: Coach Leslie Frazier said Wednesday that if Peterson could not practice Friday, he would be ruled out of Sunday's game against the Falcons. While Frazier reserves the right to change his mind on that front, Peterson missing Sunday's game remains the likely outcome. In that case, Toby Gerhart would get the start at running back for the Vikings, with Lorenzo Booker and receiver Percy Harvin in the mix for carries to a lesser degree.

Adrian Peterson: Hopes to Play Sunday

Though there are reports that Peterson expects to be able to play Sunday against the Falcons, 1500ESPN.com's Tom Pelissero believes that the running back is "still a long shot Sunday."

Analysis: Assuming the diagnosis of a high ankle sprain is accurate, we'd lean toward Pelissero's less optimistic outlook regarding Peterson's Week 12 status. Hopefully, following Friday's practice there will be added clarity to this situation. If this turns into any sort of game-time decision, fortunately, the Vikings kick off at 1:00 ET on Sunday.

Peterson (high ankle sprain) did not practice Thursday, the Minneapolis Star-Tribune reports.

Analysis: Peterson's chances of playing Sunday against the Falcons do not seem good, but we'll know more on that front Friday. Toby Gerhart would start at running back for the Vikings Sunday if Peterson is unable to play.

As expected, Peterson (ankle) did not practice Wednesday, reports the team's official site.

Analysis: Considering Peterson is dealing with a high ankle sprain, it's unlikely that he suits up Sunday.

While Peterson has a Grade 1 high ankle sprain with some ligament damage, head coach Leslie Frazier hasn't ruled him out for this week, the Minneapolis Star Tribune reports. He'll be in a walking boot the next few days with hope he can practice Friday.

Analysis: While Peterson has shown a high pain tolerance and ability to bounce back from injury, a return this week seems like a long shot - especially since the Vikings have very little incentive to rush his return. High ankle sprains typically require a minimum of several weeks to recover, so we'd think he'd be out at least this week and probably multiple weeks.

Adrian Peterson: High Ankle Sprain

Coach Leslie Frazier has confirmed that Peterson is dealing with a high ankle sprain, Jeremy Fowler of the Pioneer Press reports.

Analysis: That sort of injury is generally a week-to-week deal, but the report notes that Peterson will wear a boot for a few days and then might start light football activity as early as Friday. Either way, Peterson is very iffy for Sunday's game against the Falcons, with a game-time decision for the 1 p.m. ET contest probably a best-case scenario at this point.

Adrian Peterson: (Ankle) MRI on Tap

Peterson doesn't plan to miss significant time because of his left ankle injury, the St. Paul Pioneer Press reports. "That's not in my DNA," according to Peterson. "I'm going to try to get back as fast as I can and God willing, I'll be up and ready to run this weekend."

Analysis: Of course if Peterson's MRI on Monday determines that he has a high ankle sprain, he might have to revise that plan, as such an injury could keep keep him out for a few weeks. For now, consider the 2-8 Vikings' star back day-to-day.

Adrian Peterson: MRI on Tap for Sprained Ankle

X-rays on Peterson's sprained left ankle were negative, head coach Leslie Frazier told ESPN 1500 am Twin Cities. Peterson will have an MRI on Monday to determine how bad his ankle sprain is.

Analysis: It's still not clear if Peterson has a high-ankle sprain, which is the key information as far as his availability next week.

X-rays on Peterson's injured ankle were negative and he has a sprained ankle, head coach Leslie Frazier told ESPN 1500 am Twin Cities. He'll have an MRI on Monday.

Analysis: It's still not clear if he has a high-ankle sprain, which is the key information as far as his availability next week.

According to the Jeremy Fowler of St. Paul Pioneer Press, "someone close to Peterson" noted that an X-ray showed no break in the running back's ankle.

Analysis: We'll need verification of that report of course, but if it is accurate, then presumably determining if -- and how badly -- Peterson sprained his ankle is in order.

Adrian Peterson: Suffers Ankle Injury

Peterson was helped off the field during the first quarter of Sunday's game against Oakland with an apparent ankle injury.

Analysis: He didn't appear to be putting any weight on the injured ankle, but the Vikings haven't revealed a specific ailment just yet. Toby Gerhart would be in line for extra snaps at running back should Peterson be unable to return, but it could lead to additional snaps for Percy Harvin as well. For now, consider Peterson questionable to return.
