Minnesota Vikings running back Adrian Peterson said he “got a fair game” Friday in a hearing over his NFL-issued suspension.

Peterson was in U.S. District Court in Minneapolis as attorneys for the NFL Players Association and the NFL made their cases to U.S. District Judge David Doty, who deferred a ruling until after he considers the arguments.

The NFLPA is asking Doty to end a suspension the NFL administered in the wake of Peterson’s child-abuse case.

Peterson entered a no-contest plea to a misdemeanor charge of reckless assault in November, and NFL commissioner Roger Goodell suspended Peterson, declaring him ineligible to return to the league until April 15.

In a letter to Peterson explaining the suspension, Goodell wrote: “In order to assess your progress going forward, I will establish periodic reviews, the first of which will be on or about April 15, 2015. At that time, I will meet with you and your representatives and the NFLPA to review the extent to which you have complied with your program of counseling and therapy and both made and lived up to an affirmative commitment to change such that this conduct will not occur again. A failure to cooperate and follow your plan will result in a lengthier suspension without pay.”

The NFLPA is arguing that Peterson should be reinstated before April 15 because (1) the suspension is a retroactive application of a policy created after Peterson was arrested, (2) the arbitrator who upheld his suspension was not impartial and (3) the discipline violates the collective-bargaining agreement.

After the hearing Friday, Peterson told reporters, “I felt like I got a fair game.”

Peterson, who turns 30 in March, also said he wants to return to the Vikings. He is the team’s career rushing leader, with 10,190 yards.
