Prior to the third clash between the Panthers and the Bruins, the NHL warned both teams that the rest of the series would be scrutinized by the League. They had to make this decision following the massive scrum that emerged in the end of game 2, where a whipping total of 12 game misconducts were handed out and led to a fight between Matthew Tkachuk and David Pastrnak.
During the first period of the game, Marchand was sucker punched by Bennett, as the Bruins' captain was skating with speed to hit the Panthers' forward.
