It was late in the game, with just over ten minutes remaining in the third period, when Krug and
David Perron were involved in a scuffle in front of Tuukka Rask and the Bruins' net. After Perron ripped off his helmet and the two exchanged some punches, Krug was visibly upset, so he let his anger out with a massive hit on Thomas after skating the entire length of the ice.
