Big 12 commissioner Bob Bowlsby issued a pair of statements Tuesday announcing public reprimands for Oklahoma quarterback Baker Mayfield and four Kansas players for their actions during the Sooners-Jayhawks game last Saturday. During the pregame captains meeting, Mayfield offered to shake hands with Kansas’ captains — Joe Dineen, Dorance Armstrong Jr., Jeremiah Booker and Daniel Wise — but the quartet kept their hands behind their backs. The action sparked tension throughout the contest, eventually leading to Mayfield performing an obscene gesture and cursing toward the Kansas sideline. “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 in a statement. “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. I am grateful for the work of the Kansas administration and coaches to resolve this matter.” Kansas coach David Beaty announced Tuesday that the players who didn’t shake Mayfield’s hand will not serve as captains in the Jayhawks’ season finale against Oklahoma State.
