In the dying minutes of the second period, Senators defender Thomas Chabot scores on the powwrplsy to make it a 2-1 game, as he scores, things get rather heated; take a look.
As soon as the puck goes in, Bruins defender Parker Wotherspoon appears to say some things to Chabot leading to an exchange, Senators forward Tim Stutzle then comes to the defence of Chabot and puts Wotherspoon into a headlock.
While the officials are trying to get control of the situation, Wotherspoon punches Stützle in the mouth while the rest of the players on the ice square off. Including Bruins defender Charlie McAvoy taking on two senators players in the corner
