Vikings' Adrian Peterson suspended without pay for remainder of the 2014 NFL season

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 from the team since Sept. 17.

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