Longtime Kansas men’s basketball coach Bill Self was ejected before halftime of Tuesday night’s game against Arizona State after a heated exchange with officials over a foul call on one of the Jayhawks’ star players.

Self was assessed two technicals after arguing a call involving Jayhawks star freshman Darryn Peterson with just over six minutes remaining in the half. Peterson, coming off a screen, got tangled along the baseline with Arizona State guard Bryce Ford, and officials called a foul on Peterson as he tried to drive past Ford.
