NORMAN--Joe Mixon, the Sooner football player, has been suspended pending an investigation of allegations that he punched a woman in the face at a Norman restaurant early Friday morning.Officials of the University of Oklahoma confirmed Wednesday that the freshman running back had been suspended. On Monday, Mr. Mixon’s attorney said in a statement that his client had “done nothing wrong.” However, Kevin Finlay, the football player’s lawyer, acknowledged that Mr. Mixon was involved in a physical altercation with a 20-year-old female student at the university. The investigation into assault allegations against Mr. Mixon continued, but no charges had been filed as of yesterday. Mr. Mixon did meet with police investigators for the first time since the confrontation that could jeopardize his college football career before it even begins. “As promised, Joe met with investigators from the Norman Police Department this afternoon,” Mr. Finlay said in his statement on Monday. “Throughout the meeting, Joe continued to be forthcoming and cooperative with their investigation,” the defense lawyer added. Amelia Rae Molitor alleged that Mr. Mixon, 18, punched her in the face during a heated argument at Pickleman’s Gourmet Café on Campus Corner. A news release from the Norman Police Department said Mr. Mixon left the scene before officers arrived and they found Miss Molitor with severe injuries to her face. There is a video recording of the incident, a police department statement said, but it said “the evidentiary value of the recording prohibits its release at this time.” Miss Molitor told reporters that Mr. Mixon “broke my face in four places,” adding that she hopes he “goes to prison for years.” A great deal of hope is invested in the football player’s potential for landing a championship for the Sooners. Mr. Mixon is a five-star prospect from Freedom High School in Oakley, Calif. The Website rivals.com ranked Mr. Mixon as the No. 1 all-purpose back in the 2014 recruiting class. He attended the Sooner’s spring game in April and spent much of the afternoon signing hundreds of autographs for overjoyed fans. As the Sooners—considered a legitimate national championship contender this season—begin fall practices Thursday, they will be without the crown jewel of their 2014 signing class. A spokesman for the Cleveland County District Attorney’s Office said a decision regarding the Mixon case cannot be expected until after this week, and a spokesman for the university said the athletic department is still conducting an internal investigation. The student athlete’s attorney indicated Mr. Mixon will claim he hit the Miss Molitar in self-defense. “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,” the attorney said in a statement. “As a result of these physical attacks, Joe instinctually defended himself against further harm.” In describing Miss Molitor as “troubled,” the lawyer seemed to be alluding to her past run-ins with the law. Miss Molitor was put on probation in July 2013 after pleading no contest to a misdemeanor offense of illegal possession of pain medication and drug paraphernalia. She pleaded guilty to felony marijuana possession and three misdemeanors in March. A bench warrant was issued for Miss Molitor’s arrest July 24—a day before the confrontation with Mr. Mixon—for violating the terms of her probation in the first case. Miss Molitor wasn’t arrested Friday morning after the altercation with Mr. Mixon, however, and it was said later that day that she had gone home to Texas. A confidante of Miss Molitor told the Norman Transcript the university student she underwent four hours of surgery for her facial injuries Monday. “We are looking forward to a thorough investigation and are very much looking forward to the truth coming out,” Mr. Finlay, the football player’s lawyer, said in the statement.
