NORMAN, Okla. (AP) A University of Oklahoma student is suing the school's running back over a 2014 incident in which the player was charged with punching her in the face.

Amelia Molitor filed a complaint Friday in U.S. District Court against Joe Mixon, alleging negligence, willful and wanton misconduct, and intentional infliction of emotional distress in the confrontation at a restaurant in Norman. The suit seeks unspecified damages.

Mixon accepted one year of probation in October 2014 after being charged. In his Alford plea, he acknowledged there was likely enough evidence to convict him of misdemeanor assault while still asserting his innocence. He performed community service and underwent counseling.

Court documents don't list an attorney for Mixon who could comment about the lawsuit on his behalf.

After being suspended during the 2014 season, Mixon returned to the team last year.
