Days after a "serious altercation" in which he was being investigated for assault, Oklahoma Sooners running back Joe Mixon met with police investigators.

According to ESPN, Mixon's attorney, Kevin Finlay, said Monday's meeting was routine and maintained his client did nothing wrong. Mixon was at a local restaurant in Norman, Okla. celebrating his birthday when another Oklahoma student was apparently punched in the face, breaking it in four places.

Amelia Rae Molitor, 20, previously told the Oklahoman it was Mixon who hit her in the altercation early Friday morning. The police report said she was intoxicated, but she insists people at Mixon's table were harassing her before the freshman five-star recruit punched her.

"This past Friday morning Joe Mixon found himself in a situation where he was subjected to both verbal and physical attacks from a very intoxicated and troubled young woman. As a result of these physical attacks, Joe instinctually defended himself against further harm," Finlay said in a statement to ESPN. "As promised, Joe met with investigators from the Norman Police Department this afternoon. Throughout the meeting, Joe continued to be forthcoming and cooperative with their investigation.

"We are looking forward to a thorough investigation and are very much looking forward to the truth coming out. As we have always maintained, Joe has done nothing wrong."

A spokesman for the school said they are still conducting their own probe of the incident and the Norman Police said they had obtained surveillance footage from the restaurant. Mixon is still not charged with anything and is expected to compete for the starting running back position with the Sooners.

"Oh, absolutely, he'll have a chance to," head football coach Bob Stoops said on ESPN radio show, The Herd. "We've got other talented guys, but Joe, he's been everything we hoped he would be on campus already."
