Early on in the game between the Flames and Bruins Brad Marchand was driving toward the net as the Flames goalie made a save. In typical Marchand fashion, he gave a shove and a slash to the Flames goalie.
Pospisil popped Marchand in the face with a vicious punch. Eventually, the scrum would be broken up and penalties would be handed out. Pospisil would get a five-minute major and a game misconduct ending his day.
