At that time, Milan Lucic, allegedly threatened Canadiens forward Dale Weise as the teams exchanged handshakes, while also sharing words with Alexei Emelin and others as he proceeded down the line.
From his account, it seems that there might have been some misconception between the teams, as Montreal believed he was taunting them throughout the game with his chest-pounding gesture.
However, Lucic claims that was not the case at all, and interestingly, he admitted that he didn't even know who Weise was at the time.
