Team USA player ejected for a good clean hockey hit

Today they decided to add a 3rd. During the 2nd period of today's game between Team USA and Team Slovakia a referee decided to issue a game misconduct to Team USA's Kenny Connors. The hit was delivered within a second of the puck leaving, but it did send the Slovakian player into the boards.

The referee closest to the plau didn't call a penalty, as you can see his arm never goes up. But the other official felt this was worthy of a game misconduct for boarding.
