The NHL has already handed out some suspensions for two incidents involving hits to the head.
First, they suspended the Ottawa Senators Ridly Greig for one preseason game and one regular season game after he cross checked Pierre-Luc Dubois in the face. The Jets forward required 15 stitches afterwards.
Then they suspended Capitals defenseman Dylan McIlrath for a head shot. He received a total of 4 games (2 preseason / 2 regular season) for his shoulder to the head of Bruins forward Steven Fogarty.
The league is looking to come down harder on infractions this season, especially cross checking.
