The concussion news continued to grow worse for the NHL Tuesday, with the Philadelphia Flyers announcing that Claude Giroux would be out indefinitely with a head injury. The news comes a day after Pittsburgh's Sidney Crosby, perhaps the league's best player, was out again with a recurrence of concussion symptoms, which had kept him out of the Penguins' lineup for most of this year. Giroux's injury costs the league its leading scorer – he has 39 points in 28 games – and a star player on a team leading the Eastern Conference. It was a startling development for the Flyers, who announced Monday that Giroux's injury did not appear to be serious and that he was feeling better. They also said Monday that he would not play Tuesday night. Meanwhile, Scott Hartnell extended his goal-scoring streak to six games and Philadelphia won in Washington for its sixth straight victory, 5-1. Devils 3, Panthers 2: Ilya Kovalchuk and Patrik Elias scored in a shootout and Martin Brodeur stopped both Florida attempts, lifting the Devils over the host Panthers, 3-2. Elias and Zach Parise scored for the Devils in regulation. Brodeur made 24 saves to help the Devils rally from a two-goal deficit for their fourth win in five games. Kris Versteeg scored twice for Florida, which dropped its third straight. Jose Theodore stopped 32 shots. Canadiens 5, Islanders 3: Petteri Nokelainen scored with 6:15 remaining as Montreal recovered after giving up a two-goal lead in the third period to send the visiting Islanders to their third straight loss. Flyers 5, Capitals 1: Scott Hartnell extended his goal-scoring streak to six games, Marc-Andre Bourdon got his first NHL goal and visiting Philadelphia beat Washington to extend its winning streak to six games. Jets 2, Wild 1: Bryan Little scored a power-play goal with five minutes remaining in regulation as Winnipeg ended visiting Minnesota's seven-game winning streak.
