Last night, Rob Scuderi sent Jason Chimera skates-over-teakettle during the Kings-Jackets game. Video of the hit is available on Puck Daddy, and I won't steal his hit counter from him, so go here and watch. That's okay, I'll wait till you get back.
Scuderi was not called for a penalty, but the Jackets were outraged and Derek Dorsett jumped off the bench and went after Scuderi; Chimera ended up pulling two officials to the ice trying to get to him. Chimera ended up with a 10 minute misconduct, Dorsett with a too-many-men-on-the-ice bench minor and a game misconduct for leaving the bench.
Per the NHL rulebook, rule #45:
45.1 Clipping - Clipping is the act of throwing the body, from any direction, across or below the knees of an opponent.
A player or goalkeeper may not deliver a check in a “clipping” manner, nor lower his own body position to deliver a check on or below an opponent’s knees.
An illegal “low hit” is a check that is delivered by a player or goalkeeper who may or may not have both skates on the ice, with his sole intent to check the opponent in the area of his knees. A player or goalkeeper may not lower his body position to deliver a check to an opponent’s knees.
Moreover, because Chimera was injured - he was lucky it wasn't worse AFAIC - if this rule is invoked, Scuderi hits the showers.
45.3 Major Penalty - If an injury occurs as a result of this “clipping” check, the player or goalkeeper must be assessed a major penalty (see 45.5).
45.5 Game Misconduct Penalty - A game misconduct penalty must be assessed anytime a major penalty is applied for injuring an opponent by clipping.
I doubt intent to injure - I'm not sure Scuderi fully had his balance on this one. But, all the same....
UPDATE 10/27/09 - NHL.com reports that Scuderi has been fined for the hit, but doesn't say the exact fine.
