Lucic taunted the crowd with a sexual gesture and mimicked raising the Stanley Cup while entering the penalty box in Boston's 6-4 loss to the Canadiens.
Lucic was already a villain in Montreal after last year's playoff series, which ended with him threatening Dale Weise in the handshake line.
At 18:40 of the third period Thursday, with Boston pushing to tie the game, Lucic crushed Emelin and was given a two-minute boarding penalty. After P.A. Parenteau scored into an empty net to seal the win, Lucic was handed a misconduct for mouthing off to the officials, then flexed his muscles to the Bell Centre crowd in the penalty box. There were reports he also made a rude gesture to the fans.
The pre-game buildup was all about last spring, when the Canadiens upset Boston in seven games in the second round of the playoffs. In the handshake line after Game 7, Lucic reportedly threatened to "kill" Dale Weise and Alexei Emelin.
Weise was a healthy scratch, but the Lucic vs. Emelin animosity was a game-long subplot. The Canadiens defenceman knocked down Lucic with an open ice check early in the game.
Lucic did not speak to the media after the game.
