EDGE Analysis

Backes and Sabourin collided in the neutral zone, with Sabourin getting the worst of it and having to be removed from the ice on a stretcher. There has been no word yet on why Backes left, whether it had to do with an injury of his own or to just support Sabourin, but expect the Bruins to update Backes' situation after the game.
