Give me a break. He didn't charge from the other end of the ice, and its not like he smashed his face into the boards from behind. The fact that this hit is even being discussed as possibly suspension-worthy is ridiculous.
41.1 Boarding – A boarding penalty shall be imposed on any player or goalkeeper who checks or pushes a defenseless opponent in such a manner that causes the opponent to hit or impact the boards violently in the boards. The severity of the penalty, based upon the impact with the boards, shall be at the discretion of the Referee.
42.1 Charging - A minor or major penalty shall be imposed on a player who skates or jumps into, or charges an opponent in any manner.
Charging shall mean the actions of a player who, as a result of distance traveled, shall violently check an opponent in any manner. A “charge” may be the result of a check into the boards, into the goal frame or in open ice.
Both of those from nhl.com and they pretty much both sum up the hit
