The Capitals might get a break on Tuesday when they return to action against the Philadelphia Flyers.
With top defenseman Chris Pronger already out with a concussion, the Flyers might be without the NHLs leading scorer and No. 1 goaltender.
Claude Giroux, who leads the league with 39 points in 28 games, left Saturday nights 5-2 win over the Lightning when teammate Wayne Simmonds inadvertently kneed him in the head while trying to leap over him.
The collision occurred late in the second period and Giroux did not return for the remainder of the game.
We didn't want to put him back in there at that time, Flyers general manager Paul Holmgren said. It's a game in December. Obviously, he's one of our better players, so we'll err on the side of caution.
Giroux centers the Flyers top line and has 16 goals and 23 assists.
"Hes our best player," linemate Scott Hartnell said. He's a big catalyst for us. He's so strong on pucks, he's great defensively. Obviously, we know what he can do offensively. If he's out we're going to miss him big-time."
The Flyers may also be without goaltender Ilya Bryzgalov, who tweaked a lower body injury and left after two periods. Bryzgalov is also questionable for Tuesday.
