Oklahoma freshman running back Joe Mixon, the school's top recruit, was charged with misdemeanor assault on Friday, accused of knocking a woman unconscious with a punch that also broke several bones in her face. Mixon has not participated in team activities since July 25, when Norman police say the incident occurred at a local restaurant. On signing day, Mixon was listed as Rivals.com's No. 1 running back and 247sports.com's No. 1 all-purpose back. Oklahoma has not made a decision on Mixon's status.
