PHILADELPHIA - The Philadelphia Flyers say captain Chris Pronger will miss the rest of the season with "severe post-concussion syndrome."
The decision comes after the 37-year-old was examined in Pittsburgh by doctors John Maroon and Mickey Collins, who also treated Penguins star Sidney Crosby.
"Chris will continue to receive treatments and therapy with the hope that he can get better," Flyers general manager Paul Holmgren said in a release Thursday.
Pronger has missed the Flyers' last 11 games since coming down with what the team first described as a virus and later changed to post-concussion symptoms.
The bruising defenceman also took a stick in the eye from Toronto's Mikhail Grabovski in late October that resulted in facial trauma and caused him to miss six games.
Pronger, who had knee surgery last month, has one goal and 11 assists in 13 games this season.
The Dryden, Ont., native, who won gold medals with Canada at the 2002 and 2010 Olympics, signed a seven-year contract with the Flyers in 2009.
Pronger also won the Stanley Cup with the Anaheim Ducks in 2007.
He has 157 goals and 541 assists in 1,167 career regular-season games in 18 seasons with Hartford, St. Louis, Edmonton, Anaheim and Philadelphia.
Pronger joins a long list of NHL players suffering from concussions or concussion-like symptoms this season. Crosby returned to action last month for the first time since early January, but has since suffered a setback and is again out of the Penguins lineup.
Flyers forward and NHL points leader Claude Giroux is also out with a concussion, as is Ottawa Senators forward Milan Michalek, the league's top goalscorer, and Carolina Hurricanes sniper Jeff Skinner.
Giroux, who has 39 points on the season, took an inadvertent knee to the head from teammate Wayne Simmonds in a game Saturday.
"Claude's status remains the same," Holmgren said. "He is out indefinitely."
The Flyers took on the Canadiens in Montreal on Thursday night.
