Keith Ballard hits Corey Perry with a Legal Hit, Fights Nate Thompson

If you haven't seen this, it's worth a look. Minnesota Wild defenseman Keith Ballard hits Anaheim Ducks forward Corey Perry with a clean, hard, hip check. Unfortunately for Perry, he was knocked out of the game with a knee injury. Below is the embedded video of the fight in question.

Just for the record, last time the Ducks and Wild played, the Ducks were taking runs at the Wild players. So, they really have no room to complain about this hit.
