OTTAWA - With three of their top forwards out, the Ottawa Senators' less heralded players have been forced to step up.

So far, they've done the job.

Peter Regin, Ryan Shannon Chris Neil and Chris Campoli scored as Ottawa beat the Montreal Canadiens 4-2 Monday night, while Pascal Leclaire stopped 29 shots for his tenth win.

The Senators (20-15-4) have won both their games since losing captain Daniel Alfredsson to a shoulder injury in a Dec. 23 game against Pittsburgh. Forwards Jason Spezza and Nick Foligno are also sidelined.

Mike Cammalleri and Benoit Pouliot scored for the Canadiens (19-18-3), while Jaroslav Halak faced 27 shots and saw his four-game winning streak ended.

The energy in Scotiabank Place was palpable even during the warm-up and the 20,369 on hand weren't disappointed.

From the drop of the puck the two teams played an intense game, feeding off the crowd's energy.

The Canadiens got things started as Cammalleri, with his first in seven games, fired a shot that made it through the legs of two Senators before beating Leclaire. It was the Canadiens 20,000th goal in franchise history.

Montreal made it 2-0 midway through the period as Pouliot managed to get a shot off as he fell to the ice.

The Senators finally managed to give their fans something to cheer about as Regin jumped on a rebound in front of the net and beat Halak to cut the lead in half.

The Senators tied the game late in the second period on a power-play goal as Shannon beat Halak over the left shoulder with a shot from the point.

Ottawa appeared to take the lead in the final minute of play, but referee Kerry Fraser waved off an apparent Alex Kovalev goal due to interference with Halak.

Television replays suggested there was no contact, leaving Senators coach Cory Clouston infuriated with the call.

Neil made up for the lost goal by scoring in the third to give the Senators a 3-2 lead, but this one also needed to be reviewed.

Fisher beat Marc-Andre Bergeron to the puck along the side boards and took a shot that went off the crossbar where Neil struck it in midair to beat Halak. This time the goal was allowed.

Campoli scored an empty-net goal to seal the win.

Brian Gionta returned to Montreal's lineup after missing the last 21 games with a broken foot. He finished the game with an assist on Pouliot's goal.

Notes: Ottawa was without RW Daniel Alfredsson (shoulder, 4-6 weeks), C Jason Spezza (knee, 6 weeks), LW Nick Foligno (lower body, out indefinitely). D Erik Karlsson was a healthy scratch for the second straight game... Montreal was without D Roman Hamrlik (knee, day-today), D Paul Mara (, and RW Georges Laraque was a healthy scratch.
