Ray Emery's NHL future is again uncertain, this time due to an injury that will see him miss the rest of the season.

The Philadelphia Flyers made the announcement on Tuesday, one day ahead of the league's trade deadline.

"Ray Emery will have surgery in the near future to repair his right hip," general manager Paul Holmgren said in a statement. "He is suffering from avascular necrosis and will have a bone graft done to alleviate his hip issues. Ray will be out for the remainder of the season."

Emery started the season strongly for Philadelphia, recording a shutout in his first game and allowing just 31 goals in his first 14 appearances.

The 27-year-old had to undergo abdominal surgery in December, returning to the lineup for eight games before his most recent woes.

In 29 games this season, he is 16-11-1 with a 2.64 goals against average and a .905 save percentage with three shutouts.

Emery played in Russia last season, after discipline issues led to the Ottawa Senators buying out the remainder of his contract after three seasons as a regular with the club.

The Flyers signed the Hamilton, Ont., native to a one-year contract.

The club said a date for the surgery has not yet been set.
