Kansas basketball coach Bill Self was ejected from Tuesday night's game against Arizona State after receiving technical fouls for arguing with officials before halftime.

The ejection occurred during the first half when Self disputed a foul call involving Kansas player Darryn Peterson. Self's animated protest with the referees resulted in technical fouls that led to his removal from the game.

Arizona State capitalized on the situation and built a 20-point lead by halftime. The Sun Devils maintained their advantage throughout the second half to secure a 70-60 upset victory over the Jayhawks.

Kansas was forced to complete the remainder of the game without their longtime head coach on the sideline. The loss marked a significant upset for Arizona State against the traditionally strong Kansas program.

Self, who has coached Kansas since 2003, was described as having issues with what he perceived as inconsistent officiating during the contest. The Jayhawks were unable to mount a comeback in the second half despite the coaching staff's efforts to rally the team.
