It's not everyday that you see something like this happen at a sporting event.
The Chicago Blackhawks mascot "Tommy Hawk" got into a fight with a fan who attacked him at the game on Friday.
According to the Police, the attacker punched Tommy and then put him in a headlock.
A video of the fight went viral over the weekend and when it starts, we see Tommy turning the tables and body-slamming the guy to the floor. Then he gets in a few punches of his own. The fight is still going on when the clip ends.
