Milan Lucic gesture under review

MONTREAL -- Boston Bruins forward Milan Lucic appeared to make a vulgar gesture to Canadiens fans as he entered the penalty box late in the third period of Thursday night's 6-4 loss to Montreal at Bell Centre.

The NHL is reviewing the situation, a source told ESPN.com's Pierre LeBrun.

Lucic was given a two-minute boarding penalty at 18:40 when he hit the Canadiens' Alexei Emelin. Lucic did not agree with the call, and as he entered the box, he made a motion with his right hand and then mocked as if he was lifting the Stanley Cup.

After the Canadiens scored an empty-net, power-play goal, Lucic screamed something at the referee when he was leaving and was ejected from the game.

After the game, Lucic was not made available to the media despite numerous requests.

When Bruins coach Claude Julien was asked for his thoughts on the penalty, he said: "No comments."

On the play, Emelin turned toward the boards at the instant Lucic made contact.

On Lucic's first shift of the game, Emelin dropped the Bruins forward with a clean open-ice hit.

Lucic has been the center of attention since the now-infamous comments he made in the handshake line after Game 7 of the second-round series loss to the Canadiens last May.
