Tim Thomas made 47 saves, Daniel Paille scored twice and the visiting Boston Bruins extended their winning streak to three games with a 5-2 victory over the Ottawa Senators on Wednesday night.
Rich Peverley had a goal and an assist and Chris Kelly and Patrice Bergeron also scored for Boston, which won for the second night in a row to move into a tie with the Flyers atop the Eastern Conference standings. Andrew Ference had two assists.
Daniel Alfredsson and Jason Spezza each had a goal and an assist for the Senators, on a 2-4-2 skid despite an overtime win at Buffalo a night earlier.
Patrick Kane's goal in the second round of a shootout clinched the Chicago Blackhawks' fifth straight victory on the road, 4-3, over the Minnesota Wild in a matchup of the top two teams in the Western Conference.
Jonathan Toews also scored in the shootout after giving Chicago a lead with a goal in the third period that Mikko Koivu matched a few minutes later.
Marian Hossa and Michael Frolik gave the Blackhawks a 2-0 lead with second-period goals 89 seconds apart, but Kyle Brodziak and Matt Cullen answered for the Wild later in the period to tie the game.
Buffalo Sabres forward Ville Leino is out indefinitely after suffering what the team is calling a lower body injury.
Coach Lindy Ruff says Leino, a former Flyer, will be out "for weeks" after the player was absent from practice on Wednesday, a day after being hurt in a 3-2 overtime loss to Ottawa.
It's the latest blow to an injury-riddled team that hasn't had a healthy lineup all season. The Sabres were missing six regulars against the Senators.
The injuries have contributed in Buffalo going 3-5-3 in its last 11 games.
The slumping Carolina Hurricanes say leading scorer Jeff Skinner and key defenseman Joni Pitkanen are out indefinitely with concussions.
General manager Jim Rutherford updated the players' status in a statement issued roughly an hour after the end of Wednesday's practice.
The diagnoses are the latest blows to a team that has dropped into last in the Eastern Conference.
