Carlos Boozer Accidentally Punches Referee While Celebrating Basket (Video)

An over-exuberant fist pump can be a dangerous thing.

NBA referee Danny Crawford found that out firsthand Sunday, when Bulls forward Carlos Boozer went a little overboard celebrating an and-one layup and ended up socking Crawford below the belt. The ref took it like a champ, laughing it off on his way back up the court, but Boozer didn’t look so amused.

Check out the accidental punch in the video below.
