Montreal --

Flyers captain Chris Pronger will miss the rest of the regular season and playoffs due to severe post-concussion syndrome.

Philadelphia general manager Paul Holmgren made the announcement through a team spokesman early in the first period of the Flyers' game against Montreal on Thursday.

Pronger has been sidelined since Nov. 19.

"Chris will continue to receive treatment and therapy with the hope that he can get better," Holmgren said.

Flyers forward Claude Giroux, the NHL scoring leader with 39 points, also is out indefinitely with a concussion.
