One of the ugliest moments in the rivalry's history took place in January 2020 in Allen Fieldhouse, when a brawl erupted between KU and KSU players near the end of an 81-60 Jayhawk win over the Wildcats. The brawl started after KU's Silvio De Sousa had the ball stolen from him by KSU's DaJuan Gordon while attempting to dribble out the last few seconds of the game with a 21-point lead. De Sousa recovered to block a layup attempt and then stood over Gordon. In response to a perceived taunt, the Kansas State bench cleared followed quickly by Kansas' bench, and punches were thrown. The brawl went into the handicap seating area, knocking over fans. At one point De Sousa picked up a chair over his head, but dropped it seeing only KU players in front of him. The brawl resulted in a KU assistant coach suffering a broken arm, multiple school enforced player suspensions, and separate suspensions being handed down from the Big 12.
