MINNEAPOLIS — The NFL has suspended Adrian Peterson without pay for at least the rest of the season.

The league said Tuesday it informed the Minnesota Vikings running back he will not be considered for reinstatement before April 15 for violating the NFL personal conduct policy.

The NFL Players Association quickly announced its plan to appeal the punishment.

Peterson pleaded no contest Nov. 4 to misdemeanor reckless assault in Texas for injuries to his 4-year-old son he was disciplining. He had been on paid leave, making $690,000 each week, since Sept. 17.

Commissioner Roger Goodell announced Aug. 28 an enhanced crackdown on players involved with domestic violence.

The Minnesota Vikings this season are 4-6, having lost 21-13 to the Chicago Bears. The team had Adrian Peterson only for the first game of the season, a 20-9 victory over the New Orleans Saints.

Peterson’s teammates have said publicly that they would welcome back the star running back as soon as the league and team officials allow him to play.
