With Philadelphia mired in a seven-game losing streak, the Flyers are now down two more forwards, according to various media reports.
Philadelphia's Joffrey Lupul is expected to miss two to three weeks with a high ankle sprain while teammate Steve Downie is day to day. Flyers general manager Paul Holmgren said Downie suffered a concussion.
Lupul, who has 18 goals in 44 games this season, is expected to wear a cast for a few days, according to Flyers coach John Stevens.
"I think he hurt it pretty good there, so he could be out a while," Stevens told reporters. "He's really a dynamic player. Big. Strong. Plays both ends of the rink. It hurts with him going out."
Philadelphia is also without defenseman Derian Hatcher and forward Simon Gagne. Hatcher is likely out at least three more weeks with a knee injury while Gagne's return to the ice this season is uncertain after suffering his third concussion.
The Flyers are currently in seventh place in the Eastern Conference with 65 points but are only eight points behind first-place Ottawa. Philadelphia is also just one point ahead of Boston and Buffalo, who are tied for the eighth and final playoff spot in the conference.
