MINNEAPOLIS — The NFL has asked a federal court to reject the petition by the NFL Players Association on behalf of Adrian Peterson to have the star running back’s suspension overturned.

Attorneys for the league, in a 35-page filing Friday, wrote that U.S. labor law should prevent the court from handling a dispute already ruled on by the arbitrator for Peterson’s appeal.

The NFL argued that the NFLPA’s 74-page petition, filed Dec. 15, amounted to “nothing more than a transparent effort to re-litigate all of the issues” previously decided on by arbitrator Harold Henderson.

Commissioner Roger Goodell, through the collective bargaining agreement between the two parties, has the power of discipline, the league wrote.

The hearing is scheduled for Feb. 6 in front of U.S. District Judge David Doty. The NFL suspended Peterson through at least April 15 for the child-abuse case he was involved in, and Peterson’s appeal was denied by Henderson, a former a league official.
