Nothing got hurt except his pride, and I'm pretty sure Tyler Hansbrough doesn't have any of that anyway.
Did he get injured? I thought he was just a little roughed up, and sad, brough. Did he actually get hurt? That isn't what anyone is laughing about even if he did. I'm pretty sure it's just a joke about how he was posed after having been dunked on massively... during what someone already recognized as the high point of the game.
