Anderson out at least one week for Senators with knee injury

Senators coach D.J. Smith said the 38-year-old goalie tweaked his knee before leaving in the first period of a 4-3 loss to the Philadelphia Flyers at Wells Fargo Center on Saturday. Anderson allowed two goals on six shots and is 5-8-0 with a 3.01 goals-against average and .901 save percentage in 16 games (14 starts) this season.

"I was expecting a big game out of him in [Philadelphia] and for him to get hurt, it's hard when you keep getting nagging injuries, you can never really get into a groove," Smith said.

Goalie Anders Nilsson is expected to start for the Senators against the Boston Bruins at Canadian Tire Centre on Monday (7:30 p.m. ET; TSN5, RDS, NESN, NHL.TV). Ottawa (12-17-1) has lost six of its past seven games after going 7-2-0 in its previous nine.

Goalie Marcus Hogberg was recalled from Belleville of the American Hockey League. The 25-year-old, who was a third-round pick (No. 78) by the Senators in the 2013 NHL Draft, was also recalled earlier in the season when Anderson previously was injured and is 0-1-0 with a 1.82 GAA and .925 save percentage in two games (one start).

Hogberg made 24 saves on 26 shots in a 3-1 loss to the Calgary Flames on Nov. 30.

"He's a guy that I think is going to be a good NHL goalie, given enough opportunity, and he's going to get another chance to start," Smith said. "So, instead of looking at it as a negative, I look at it as a positive, we'll get another look at him."
