On the same day the NHL announced that Colin Campbell was stepping down as the head of supplemental discipline for the league, the end of the first period left something for the league to review. Given the conflict of interest during the Stanley Cup Finals, NHL VP Mike Murphy was already handling supplemental discipline and Alex Burrows gave him something to review.
During a scrum to end the first period is certainly appears that Alex Burrows of the Canucks at least attempts to bite the finger of Bruins forward Patrice Bergeron. Bergeron is clearly telling the officials he was bitten as he attempts to show the referees his bare finger before heading to the locker room.
In the past the NHL has suspended for such acts and should do so again if they deem that Burrows did bite, or even attempt to bite Bergeron even though this is the Stanley Cup Finals.
