With his team up by two, McCaffery took issue with a call on junior center Gabriel Olaseni under the bucket and launched into a full-blown tirade.
He was given two technical fouls and ejected from the game, leaving the Hawkeyes to essentially fend for themselves against an undefeated Badgers squad at home.
Michigan State fans, like Wisconsin fans, are familar McCaffery's inability to control his temper.
He infamously smashed a chair in response to getting T'd up in a Jan. 2012 game against the Spartans.
McCaffery's ejection proved to be costly, as the Badgers beat the Hawkeyes, 75-71, and continued their undefeated season.
