NORMAN—After charges were filed against him by a county prosecutor, Joe Mixon was suspended for a year by University of Oklahoma officials.The nationally-heralded star running back signed by the Sooners won’t get to make his expected-to-be tremendous mark his freshman year as a Sooner. Mixon pleaded not guilty to a misdemeanor at his appearance at the Cleveland County Courthouse. “As the university has demonstrated in the past,” Athletic Director Joe Castigilone and Coach Bob Stoops said in a statement,” we are committed to winning the right way. “As an example to others, OU sets the highest possible standards for its student athletes, coaches and staff.” Mixon was removed from the roster immediately and will be excluded from all team activities during the suspension. Mixon, who had been expected by many to lead the Sooners to a national championship this year, will be permitted to continue as a student at the university and will still be eligible for financial aid. Speaking after the Sooners’ practice Monday night, Stoops wouldn’t say much more than what was in the statement. “We made a decision here today that was announced, and that’s all I’m going to say about it,” Stoops said. “I can’t say anything else about it.” Mixon faces charges stemming from a July 25 altercation at a Norman restaurant. Released without posting bail, the star running back waived a formal reading of the charge at the hearing, which lasted about 10 minutes. His next court appearance is scheduled for Sept. 23. Mixon was charged with one count of an “act resulting in gross injury” after an incident at Pickleman’s Gourmet Café, which is just north of the university campus. Amelia Rae Molitor, 20, an student at the school, alleged Mixon punched her once in the face, resulting in four broken bones. The probable cause affidavit, citing surveillance video taken of the incident stated Molitor pushed Mixon and the running back lunged at her, drawing a slap. Mixon then retaliated with a punch that knocked Molitor into a nearby table and then onto the floor, where she laid motionless as Mixon left the scene, according to ta court affidavit. Earlier Monday, David Boren, president of the university, Castiglione and Stoops met with Cleveland County District Attorney Greg Mashburn in Mashburn’s office. Mashburn, speaking in a radio interview with WWLS later in the day, said the three met with Mashburn to “make sure they had the whole story.” At the hearing, Cleveland County District Judge Steven Stice ordered neither side to show the surveillance video to anyone not directly involved in the case. Mixon’s attorney, Kevin Finlay, asked that the order also include law enforcement. Cleveland County Assistant District Attorney Tyler Box asked for a $1,000 bail, but Stice agreed with Mixon’s attorneys that he should be released on his own recognizance. “Frankly, your honor, he has never been in a courtroom in his life,” Finlay told Stice during the bail discussion. Mixon was ordered to have no contact with Molitor. Mixon, with a pair of stars cut into the hair on the side of his head, spoke just once during the proceeding, quietly answering a question from the judge. Earlier in the day, Mixon’s attorneys had requested a special arraignment outside the regularly scheduled 1:30 p.m. misdemeanor arraignments. Stice denied the request. Before the hearing started, Mixon and his attorneys went to a back room of the courthouse before appearing in front of the judge. Mixon sat next to his other Lawyer, Matt Swain, talking a bit before the proceeding began and fidgeting nervously in his chair Mixon has not participated in practice for the Sooners since the incident, which happened a few days before the start of preseason camp. Mixon was the No. 1 all-purpose back in the country in the 2014 class by rivals.com when he committed to the Sooners two days after the Sooners beat the University of Alabama in the Sugar Bowl in January. He attended the Sooner’s spring game, and spent much of the game signing autographs and taking pictures with fans.
