The Big 12 issued public reprimands to the four Kansas football players who served as game captains and refused a shake hands with Oklahoma captains before their game on Saturday, and to Sooners' quarterback Baker Mayfield.
Mayfield, one of the OU captains, was reprimanded for an inappropriate gesture, yelling profanity toward fans after scoring a third-quarter touchdown.
"Mr. Mayfield's actions are unacceptable and should not be tolerated," Big 12 Commissioner Bob Bowlsby said.
Bowlsby directed a similar comment to Kansas players Joe Dineen, Dorance Armstrong Jr., Jeremiah Booker and Daniel Wise, who refused to shake hands with Mayfield, who had extended his hand, during the captain's meeting.
"The refusal of these student athletes to shake an opponent's hand during the pregame ceremony is contrary to tradition and inconsistent with common courtesy," Bowlsby said. "The pregame handshake among team captains is symbolic of good sportsmanship. This breach of protocol is not in keeping with the standards of the Big 12 Conference."
