A federal judge is overturning the appeal ruling against suspended Minnesota Vikings running back Adrian Peterson.

The former NFL MVP was suspended in November after pleading no contest to child abuse charges for disciplining his four-year-old son with a tree branch last May.

After his appeal was denied, the Players' Association filed a lawsuit against the NFL on Peterson's behalf. The union claimed he should not have been subject to the league's new, tougher personal conduct policy since it was implemented after Peterson's case. The NFL says it will now review this latest decision.

Peterson wasn't due to be considered for reinstatement by the NFL until April 15th. The union is calling the judge's ruling "a victory for the rule of law, due process and fairness."

The 29-year-old, two-time rushing champ played just one game last season before being placed on the commissioner's exempt list while the legal process played out. Peterson reportedly now wants to play for another team, saying the Vikings didn't support him. (Metro Networks Inc)
