A federal judge has cleared the way for Minnesota Vikings running back Adrian Peterson to be reinstated.

U.S. District Judge David Doty issued his order Thursday, less than three weeks after hearing oral arguments. Doty overruled NFL arbitrator Harold Henderson’s previous denial of Peterson’s appeal.

The league suspended Peterson through at least April 15 for his involvement in a child abuse case. But Doty said in his 16-page ruling that Henderson “simply disregarded the law of the shop and in doing so failed to meet his duty under the” collective bargaining agreement.
