Boston Bruins forward Milan Lucic appeared to make an obscene gesture at Montreal Canadiens fans on his way to the penalty box Thursday night.

The incident is under review by NHL vice president of hockey operations Mike Murphy, according to ESPN's Pierre LeBrun.

Lucic took a costly boarding penalty with 80 seconds remaining in the third period of a one-goal contest. He reacted to the jeers from Habs fans by appearing to make a lewd gesture - you can watch a video of the incident - after which he mimed a Stanley Cup raise:

Lucic was not particularly happy on his way out of the penalty box, following Montreal's empty-net goal in the 6-4 win.

For that late-game tantrum Lucic was assessed a game misconduct.

Lucic was not made available to the press following the game, and Bruins PR didn't offer reporters an explanation.
