The Florida Panthers could be without Roberto Luongo for a while as the goalie deals with a lower-body injury, according to head coach Bob Boughner.

"It's going to be an extended period of time," Boughner said after practice Monday. "Whether that's three weeks, four weeks, five weeks, that's going to (depend on how) his rehab goes, that kind of thing. (He's) definitely out for a while."

Boughner added the injury isn't related to Luongo's surgically-repaired hip.

Luongo underwent an MRI after exiting Monday's game against the New York Islanders with the apparent injury. In 15 appearances this season, he has a 6-6-1 record and .928 save percentage.

Goaltending duties will now fall primarily to James Reimer (4-6-3, .892 save percentage), while Harri Sateri has been recalled from the AHL to serve as backup.
