Once again, Craig Anderson could have used some run support.

The Senators goalie pitched another perfect second and third period, shutting out the Montreal Canadiens with his team trailing by a goal.

And once again, his teammates couldn't make up the difference.

And so it was that the Senators left Bell Centre with a 2-1 loss, their second in a row since top centre Jason Spezza's back surgery Friday.

The Senators would not confirm after the game that centre Stephan Da Costa was being recalled from Binghamton, but don't be surprised if he is.

While they won two games without Spezza early last week, the Senators have scored just once since he went under the knife.

Anderson, meanwhile, hasn't given up a goal past the first period in any of his eight starts this season. It was also just the second game in which he has allowed more than one goal.

"We thought we did enough. We played our hearts out," said Anderson.

"I think we generated enough (scoring chances)," he said, making it clear he thought the officiating was the main part of the game story by adding: "You guys can fill in the rest."

The Senators and Habs tied in shots with 33.

What would have been Andre Benoit's first NHL goal was waved off when it was ruled that Jakob Silfverberg was guilty of goalie interference on a play early in the third.

Replays showed contact was minimal.

"I feel I might have bumped him a little bit, but I feel that was after the puck went in. I haven't seen the replay of it, so I'm not 100% sure," said Silfverberg.

Was he pushed?

"I don't know, I just feel like there was a lot of people in there, but I feel I was in safe ice."

The Senators, who are now 5-3-1, begin a four-game home stretch when they face the Buffalo Sabres Tuesday.

Erik Cole's second goal of the season, three seconds after the expiration of a Daniel Alfredsson penalty, put the Habs ahead 2-1 at the 11:29 mark of the first period Sunday.
