Crosschecked a ref in the back on the opening faceoff tonight - there was a bit of a scrum and at the start and Hansen skated over and crosscheked him. It did not look like he was aiming at anyone else. He never got a penalty, as the ref wasn't sure who had did it.

I don't think Hansen has a history, but you have to give him something - you don't intentionally hit the ref. Period.
