The Flyers aren't talking, but CSN Philadelphia's Tim Panaccio cites a person in the know:
Pronger left Game 1 of this series nearing the two-minute remaining mark of the third period and did not return. He appeared to be fine on Sunday, though moving with a slight limp, which is not uncommon for any player this time of year.
Could he have pulled his hamstring while favoring his back? That seems to be one possibility here. The Flyers aren’t talking, but Pronger is expected to return to the series for Game 3 on Wednesday in Boston.
Flyers general manager Paul Holmgren would not comment other than to say the defenseman has an undisclosed injury..
He missed Monday morning's skate, but Pronger was not listed the team's injury update. Pronger has one point and was a minus-3, averaging 13 minutes, 55 seconds over the three playoff games he played.
The Bruins lost a defenseman of their own, Adam McQuaid, to a scary injury late in the first period. McQuiad attempted to deliver a hit to Flyers forward Mike Richards, who ducked the collision. McQuaid collided awkwardly with the boards headfirst and lay on the ice for a couple minutes before he was helped off the ice.
McQuaid, whose injury was not disclosed, was transported to an area hospital for observation. The Bruins announced that McQuaid would travel back with the team on Tuesday.
