NORMAN, Okla. — The Sooners suspended Joe Mixon for Thursday's game at Iowa State.

Mixon's attorney told FOX23 sports director Nathan Thompson OU suspended the sophomore running back because he tore up a parking ticket on campus and threw it to the ground in front of the parking attendant.

In a news release sent out late Thursday night by OU, Mixon said "I regret that I did not respond appropriately to parking attendants and understand and accept the consequences."

Mixon's attorney Blake Johnson told FOX23 his client was frustrated, but Johnson says, as far as he knows, no one is accusing Mixon of saying anything profane or inappropriate to the parking attendant.

Bob Stoops said in a statement that "OU sets very high standards and they must be met by all of our student-athletes."

Mixon was suspended from the team his freshman year after punching a female OU student in the face.

Mixon returned to the team last season. This season he has been one of Oklahoma's best players. He leads the team in rushing averaging nearly 102 yards a game. He's also second on the team in receiving.

With Mixon's suspension and Samaje Perine's injury, OU will only have one scholarship running back for Thursday's game at Iowa State -- freshman Abdul Adams.
