Update (8:03 ET): The Flyers' official team website has published a statement from GM Paul Holmgren confirming the report. The statement in full:
“After consultation with respected concussion specialists Dr. Joseph Maroon and Dr. Micky Collins, it is the opinion of both doctors that Chris is suffering from severe post concussion syndrome. It is the recommendation of Doctors Maroon and Collins that Chris not return to play for the Philadelphia Flyers for the remainder of the 2011-12 season or playoffs. Chris will continue to receive treatment and therapy with the hope that he can get better.”
Philadelphia Flyers captain Chris Pronger visited two Pittsburgh-based neurologists on Wednesday for details on a head injury that featured reported concussion-like symptoms. According to a tweet from Philadelphia Daily News Flyers beat reporter Frank Seravelli, the report from the neurologists was as unfavorable as it gets, and Flyers general manager Paul Holmgren says that Pronger is done for the season.
