Minnesota Vikings running back Adrian Peterson has been suspended three games by the NFL for violating the league’s substance abuse policy, the league announced Friday.
The suspension is effective for the next five games.
Peterson will have one game to comply with the suspension, but he must meet the league criteria for substance abuse.
The Vikings had a bye in Week 8.
The team has three weeks to comply before Peterson can play again.
Peterson had a history of concussions.
NFL spokesman Greg Aiello said the league found “no clear and convincing evidence” that Peterson had suffered a concussion, and that the league believes Peterson has had a full recovery from the concussion.
Peterson is the NFL’s all-time leader in rushing touchdowns (1,926), yards (2,087), rushing touchdowns in a season (1), rushing yards per game (3.03) and rushing touchdowns allowed (3).
He has 2,096 rushing yards and 14 touchdowns.
Peterson’s absence is the first since the Vikings defeated the Washington Redskins 49-13 in Week 7.
Peterson, who missed the final three games of the season because of a concussion and had surgery on his back, returned to practice Wednesday.
He has 1,936 rushing yards, 17 touchdowns and four interceptions.
“Adrian has always been a positive leader and a positive teammate, and I’m grateful to the Vikings organization and the team doctors for their patience during his concussion,” coach Mike Zimmer said in a statement.
“Our fans and coaches have also always been great supporters of Adrian and I thank them for their support throughout this difficult time.”
Peterson is in the final year of a five-year, $48 million contract.
He is the Vikings’ highest-paid player.
He had 1,300 yards rushing in 2014.
He’s had 11 fumbles and one fumble recovered in six games this season.
Peterson has missed the Vikings season opener because of the concussion, the Vikings have not won a game since Nov. 26, 2010, and they have lost eight of 10.
He was charged with four misdemeanor counts, including driving while intoxicated, driving while under the influence of alcohol and resisting an officer without violence.
He will be in court again Dec. 7.
The NFL also fined Peterson $2,500 for driving under the speed limit in May, a $500 fine for a DUI in May and a $2 and a half for failure to stop for police.
Peterson was arrested for driving while impaired by alcohol in March.
He pleaded guilty to the DUI and had a court date scheduled for March 23.
He appeared in court for the court hearing, but the court did not set a date for his court appearance.
Peterson also pleaded guilty in October to the misdemeanor driving under influence charge for the second time in three years.
Peterson returned to the Minnesota Vikings in March and finished the season with 1,819 rushing yards.
He became the third player in NFL history to rush for 1,000 yards and rush for at least 1,500 yards in the same season when he rushed for 1.1 yards per carry.
