Mike Cammalleri scored the Canadiens the 20,000 goal in the franchise's storied history on Monday, but goals from Peter Regin, Ryan Shannon, Chris Neil and Chris Campoli led banged-up Ottawa to 4-2 victory.
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.
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.
