The Panthers lost defenseman Erik Gudbranson for at least a few weeks after he needed surgery to repair a fractured orbital bone. Gudbranson was struck hard in the face by a puck during last Friday's loss in Winnipeg.
Gudbranson could be out a month with the injury. He had surgery Monday afternoon in Boca Raton.
"We were just on a roll and you don't like to lose players at all,'' GM Dale Tallon said. "It's just the nature of the beast. It's a bad break.''
The Panthers replaced Gudbranson with rookie Alex Petrovic. The 21-year-old was a second round pick the same year Gudbranson was the third overall pick at the Los Angeles draft in 2010.
-- Winger Scottie Upshall left Monday's game with an undisclosed upper body injury. Tallon said he likely wouldn't know the extent of the injury until Tuesday.
"He's going to get some tests [Tuesday] morning,'' Horachek said. "We'll see where he is.''
