BUFFALO, N.Y. — Ville Leino scored 4:43 into overtime to lift the Philadelphia Flyers to a 5-4 victory on Sunday and force Game 7 of their first-round playoff series against the Buffalo Sabres.

Danny Briere scored twice while Brian Boucher stopped 24 shots in the latest Flyers goalie shuffle. Boucher took over to start the second period after Michael Leighton allowed three goals on the first seven shots he faced. Scott Hartnell had a goal and assist and James van Riemsdyk also scored for the Flyers, who overcame a two-goal deficit while drawing upon Chris Pronger's presence.

The gritty defenseman played sparingly in his game after missing 21 with a broken right hand.

Thomas Vanek scored twice for Buffalo, while Rob Niedermayer and Nathan Gerbe also scored.

Game 7 is in Philadelphia on Tuesday.
