Adrian Peterson's suspension is over.
The Minnesota Vikings star running back was informed Thursday that, effective Friday, the NFL has reinstated him as an active player and that he may participate in all team activities.
Peterson, the league's most valuable player in 2012, was suspended without pay Nov. 18 and for the remainder of the 2014 season for violating the league's personal conduct policy. Two weeks earlier, he pleaded no contest in Texas to reckless assault on his 4-year-old son, whom he had disciplined by striking with a tree switch.
In a letter to the player Thursday, NFL Commissioner Roger Goodell informed Peterson he is expected to fulfill his remaining obligations to authorities in Minnesota and Texas, as well as maintain an ongoing program of counseling and treatment.
According to the NFL, Goodell reminded Peterson that his continuing participation in the league "depends on his avoidance of any further conduct" that violates league policy. Any further violations, the league said in a news release, would result in additional discipline that could include suspension without pay or banishment from the NFL.
