Pierre LeBrun/ESPN.com - Chris Pronger's timetable for a return to play got murky Friday when the Flyers announced he was out indefinitely because of concussion-like symptoms.
Pronger had knee surgery in late November, which was expected to keep him out about four weeks. But now his return has no fixed date.
"While Chris' knee is improving, he has struggled with other issues that are concussion-like symptoms," Flyers general manager Paul Holmgren said in a statement released by the team Friday.
"Chris will see Dr. Joe Maroon and Dr. Mickey Collins on Wednesday, December 14th in Pittsburgh for further evaluation. Chris will be out indefinitely."
