Penguins' Comeau bloodies Coyotes' Campbell with dangerous hit

Pittsburgh Penguins forward Blake Comeau was ejected from Saturday's matinee versus the Arizona Coyotes for injuring blue-liner Andrew Campbell with a dangerous hit on the forecheck. 

Comeau didn't go directly through the back, but his contact forced Campbell face-first into the stanchion, leaving the rookie defenseman bloodied.

Campbell did return to the game.
