Boston Bruins forward Shawn Thornton was fined $2,820.52 for unsportsmanlike conduct during Game 5 of Saturday night's Eastern Conference semifinal series against the Montreal Canadiens, the NHL announced Sunday.

Thornton sprayed Canadiens defenseman P.K. Subban with a water bottle while play was in progress at 19:13 of the third period. Subban had the puck and skated by the Bruins' bench when Thornton sprayed Subban in the face.

No penalty was assessed on the play.

"I obviously got caught up in the moment," Thornton said in a statement after the game. "I'll pay the fine and obviously agree with what the league does there. I'll pay the fine and move on. I'm sorry that the silly incident kind of overshadowed how my teammates played, the great win and how good the series has been.

"I think that there's definitely more important things that we could be focusing on. I got caught up in the moment and probably shouldn't have done that. Move on and get ready for Game 6. Pay the fine and hopefully have a good showing."

The fine is the maximum permitted under the CBA. The money goes to the Players' Emergency Assistance Fund.

The Bruins took a 3-2 lead in the series and can eliminate the Canadiens on Monday night.
