The struggling Florida Panthers will be without goaltender Roberto Luongo and right wing Valeri Bure for the rest of the season, the team announced Thursday.

Luongo suffered a torn ligament in his right ankle early in the first period of Monday night's loss to Montreal. He will not require surgery and is expected to begin rehabilitation immediately.

Bure underwent surgery Monday to repair cartilage damage in his right knee and will begin rehabilitation in a few weeks.

A former first-round draft pick, Luongo was 16-33-4 with a 2.77 goals-against average and a .915 save percentage in 58 games.

Bure, who suffered the injury on March 17 with Ottawa, also missed 37 games earlier this season after undergoing arthroscopic surgery on the same knee. The younger brother of recently traded sniper Pavel Bure, Valeri Bure had just eight goals and 10 assists in 31 games.

"It is disappointing that neither player will be able to return this season," general manager Chuck Fletcher said. "But it's good news that both injuries are minor and the long-term prognosis is great for both Roberto and Val."

Florida recalled goaltender Wade Flaherty and right wing Rocky Thompson from Utah of the American Hockey League to fill the roster spots.

The Panthers are struggling through another disappointing and are next-to-last in the Eastern Conference at 19-38-7-5.
