"It's not good," Emery said Tuesday night. "It's not something that I expected to happen. I'm 27 years old, and didn't even think I had played my best hockey so far. But, things pop up, and you have to work through them."
Emery signed with the Flyers over the summer after a one-year stint in Russia and the Kontinental Hockey League. Emery had worn out his welcome in Ottawa after leading the Senators to the Stanley Cup finals. He skipped practice, tangled with teammates and made a reputation as a fighter.
In his first season with the Flyers, Emery went 16-11-1 with a 2.64 goals-against average and .905 save percentage. He had three shutouts.
Emery will be a free agent this summer and the Flyers had talked earlier this year about a possible extension. Those talks are now on hold. Emery hoped to return if he can recover from the surgery.
"I'd love to, but this is quite the procedure, though," he said. "I'm sure if I get a chance to come back and play I will have to prove myself. I love playing here, I love the guys and I love the city. Its a great thing to be a part of."
Flyers GM Paul Holmgren said Tuesday that Emery's surgery has not been scheduled.
"He is suffering from avascular necrosis and will have a bone graft done to alleviate his hip issues," Holmgren said in a news release.
With Emery out, the Flyers may look to trade for a goalie ahead of Wednesday's 3 p.m. ET trade deadline, although Michael Leighton has played well for the team.
Backup Brian Boucher is only 4-11-1. Boucher led the Flyers to the Eastern Conference finals in 2000, but bounced around before returning to Philadelphia. The Flyers are trying to win their first Stanley Cup since 1975.
Emery hoped the injury wasn't career ending.
"The success is kind of considered being mobile, not playing professional sports," he said. "It is something that I have to get done, and after that Ill do my best to get back."
