GM: Latavius Murray deal means Adrian Peterson's Vikings career over

Peterson's ups and downs since winning MVP (1:19)

Since he earned the MVP award for his performance in 2012, Adrian Peterson has dealt with a string of successes and failures, culminating in GM Rick Spielman's saying that Peterson's career with the Vikings is over. (1:19)

Minnesota general manager Rick Spielman confirmed to reporters Thursday that running back Adrian Peterson -- whom Spielman described as one of the greatest Vikings ever -- will not be back with the team.

The move seemed inevitable when the Vikings signed running back Latavius Murray to a three-year, $15 million deal on Wednesday night.

Spielman said he texted Peterson at 1 a.m. on Thursday morning and informed him of the Murray deal.

"With us signing Murray, Adrian will move on elsewhere," Spielman said on a conference call with reporters. "Adrian is probably going to go down as one of the greatest Minnesota Vikings in team history...he'll always be a Viking, I know, to the fans and the people in this building. And he will always have a special place in this franchise and we are very fortunate that we were able to have Adrian Peterson spend most of his career as a Minnesota Viking."

Peterson, who ranks 16th in NFL history with 11,747 rushing yards, became an unrestricted free agent on March 9 after the Vikings decided not to pick up their option, which would have paid him $18 million, including a $6 million roster bonus.

Peterson visited with the Seahawks earlier this week, but they signed Eddie Lacy. ESPN's Josina Anderson reported earlier this month that Peterson might be interested in the Raiders because of the team's stout offensive line. It is not known if that interest is mutual.

In January, Peterson said if the Vikings cut him loose, he could see himself playing for the Texans, Buccaneers or Giants.

Peterson turns 32 next week and played just three games last season because of a torn meniscus. He carried 37 times for 72 yards.

He returned in less than three months from his Sept. 18 injury to play against the Colts on Dec. 18. He sat out the Vikings' final two games because of an adductor strain he suffered in his first game back.

The Vikings had left the door open for Peterson to return -- at a much lower price -- to the team that drafted him in 2007 with the seventh overall pick.

Peterson, whose career rushing yards rank second to Frank Gore (13,065) among active players, has limited passing-game skills. He has little experience running out of the shotgun or pistol formations that most teams favor in the current pass-heavy NFL.

He has failed to eclipse 40 carries in two of the past three seasons because of suspension and injuries. He suited up only once in 2014 because of a child abuse case.

Even with the league-leading 1,485 yards he rushed for in 2015 -- and factoring in his receiving totals -- Peterson has cost the Vikings about $18,000 per yard over the past three years.

Since recovering from ACL reconstruction on his left knee to rush for 2,097 yards in 2012 and win the NFL MVP award, Peterson has expressed defiance toward the evidence that running backs wear down by age 30. He has long said he believes he can play deep into his 30s.
