(Boston, MA) - The latest goaltending injury jumped up and bit the Philadelphia Flyers in the second period of Monday night's Game 5, as they fought to once again stave off elimination against the Boston Bruins.

Brian Boucher, who got the Flyers into the playoffs with a shootout win over the New York Rangers on the final day of the regular season and then engineered a five-game series win over the New Jersey Devils in the Eastern Conference Quarterfinals, went down 4:35 into the second after a scramble around his net.

Flyers defenseman Ryan Parent fell on top of Boucher's left leg while it was caught underneath him after he had just stopped a shot by Miroslav Satan from in tight. Teammate Chris Pronger had to help him off the ice. Boucher had stopped all nine shots he faced before departing.

Michael Leighton, who returned as Boucher’s backup starting on Monday and hadn’t played in a game since suffering a high ankle sprain against Nashville on March 16, came on in relief. Leighton began the season with the Carolina Hurricanes and went 16-5-2 after the Flyers claimed him off waivers following an injury to starting goalie Ray Emery.

Leighton, who was making his debut in the Stanley Cup Playoffs, stopped all 14 shots against him to preserve the shutout. The Flyers held on for a 4-0 win on goals by Ville Leino, Scott Hartnell and Simon Gagne (two), and now trail the best-of-seven series three-games-to-two.
