Chris Pronger out for Game 4

The Philadelphia Flyers played Game 4 against the Buffalo Sabres on Wednesday without Chris Pronger.

Coach Peter Laviolette wouldn't give an update on when Pronger will return.

"I can't shed absolutely any light on that," Laviolette told NHL.com. "Not allowed."

The 36-year-old defenseman, out with a broken hand, remained on the ice after the Flyers' morning skate Wednesday taking part in a conditioning scrimmage with three players who haven't seen playoff action yet, plus two assistant coaches.

The Flyers lead the Eastern Conference quarterfinal series 2-1.
