Newhook was not assessed a penalty which was the wrong call and made the Sharks team even more upset than they already were. In response to the non-call Erik Karlsson took off his helmet from the bench and threw it on the ice in disgust. The referees than gave Karlsson a ten-minute misconduct for throwing his helmet. Karlsson commented after the game that he thought the refs missed an obvious call, which they did.
It was certainly a night to forget for the Sharks and the non-call just seemed to really frustrate Karlsson. I don't blame him one bit for his actions and can totally understand his frustration. Either way, the call wouldn't have changed the outcome of the game. Hopefully Karlsson will be OK and he can continue the great season he's been having personally despite another lousy year for San Jose.
