MINNEAPOLIS - The NFL Players Association's attempt to have Minnesota Vikings running back Adrian Peterson reinstated has been taken under advisement by a federal judge.

U.S. District Judge David Doty heard arguments from the NFLPA and the NFL on Friday. He did not provide a timetable for his decision.

Peterson has been suspended at least through April 15 after he was charged in a child abuse case last year, a case he resolved with a plea bargain.

NFLPA attorney Jeffrey Kessler said arbitrator Harold Henderson's rejection of Peterson's appeal was biased. Dan Nash, a lawyer for the league, said the union is simply is seeking to "re-litigate" the appeal and is bound by the collective bargaining agreement to the arbitration.

Peterson said afterward he felt he had "a fair hearing, for once."
