Oklahoma Sooners starting quarterback John Mateer is facing allegations of violating NCAA rules by betting on college sports. Social media users discovered Venmo transactions with descriptions referencing a UCLA vs. USC game. Mateer denies the allegations, claiming the descriptions were inside jokes. The NCAA prohibits college athletes from betting on college sports. Oklahoma officials are aware of the Venmo activity but haven't launched an investigation. Mateer's alleged bet concerned the November 2022 game between UCLA and USC, won by USC. He transferred to Oklahoma after playing one game for Washington State.
