VOORHEES, N.J. (AP) -Flyers defenseman Derian Hatcher will undergo surgery to repair cartilage damage in his right knee and will miss two to four weeks.
The 35-year-old Hatcher, who had his streak of 107 consecutive games recently snapped because the knee was bothering him, said he aggravated the injury lifting weights.
"I've had problems with it the past 10 years probably," Hatcher said after the Flyers practiced on Wednesday. "It's probably closer to four weeks (recovery) because it's had trauma before. The tough thing about getting injured is it sets you back. Instead of being where you're at, you're almost starting over."
The Flyers called up Nate Guenin from their American Hockey League affiliate Philadelphia Phantoms to fill Hatchers roster spot. Guenin played nine games with the Flyers last year.
The Atlantic Division-leading Flyers (7-3) also will play the next two games without forward Simon Gagne and defenseman Randy Jones.
Gagne will miss two more games because of the vision problems and dizziness he's experiencing from a hard hit suffered last week.
"He was better, but still not at the baseline that he needs to be at," Flyers general manager Paul Holmgren said.
Holmgren said he hoped Gagne, who has four goals and eight points this season, would return next week. Gagne will miss Thursday's game at Montreal and Friday's game at Washington.
Scott Hartnell has been moved up to take Gagne's spot on the Flyers' top line with Daniel Briere and Mike Knuble.
