Adrian Peterson's season is finished.
The Minnesota Vikings made that official Saturday afternoon when they downgraded the Pro Bowl running back from doubtful to out on the injury report.
That means Peterson will miss Sunday's regular-season finale against the Detroit Lions at the Metrodome. That, of course, will be the Vikings' last game in the building before it's torn down to make room for a new stadium.
The move comes as no surprise, given that Vikings coach Leslie Frazier said Friday that the 2012 NFL MVP would not play, "unless something dramatically changes."
Peterson has been hampered by a mid-foot sprain he suffered in a Dec. 8 loss at Baltimore and a groin pull he's played through in the second half of the season.
He did not play two weeks ago in the Vikings' victory over Philadelphia but returned last Sunday to play in a blowout loss at Cincinnati. Peterson admitted he wasn't at 100 percent in that game and had only 10 rushing attempts, including one in the second half.
Backup running back Toby Gerhart already has been declared as out because of a hamstring injury for Sunday, meaning Matt Asiata likely will get his second career start. Asiata missed last week's game because of an ankle injury but was listed as probable for Sunday.
Peterson, who won the NFL rushing title last season by having the second-best yardage total in league history (2,097 yards), is third in the NFL with 1,266 yards. Philadelphia's LeSean McCoy leads the league with 1,476 yards on the ground and Kansas City's Jamaal Charles is second with 1,287 yards.
