VOORHEES, N.J. -- Goalie Michael Leighton practiced Sunday here at SkateZone, the Flyers' suburban practice rink, as starter Brian Boucher's backup, but forward Danny Carcillo, who was injured in the Flyers'5-4 overtime victory Friday night, did not practice and may miss Game 5 Monday in Boston (7 p.m., VERSUS, TSN2).
The Flyers staved off elimination Friday night when Simon Gagne, who missed the previous four games with a broken foot, scored at 14:40 of overtime. The Flyers now trail the , 3-1.
If Carcillo, who sat on the bench for the third period and overtime, can't play, his likely replacement is Jon Kalinski, a left wing who can play center and who brings some grit. That's necessary when you're replacing a player nicknamed "Car Bomb."
Carcillo was rocked early in the first period by a check thrown by Bruins defenseman Johnny Boychuk, but played on through the final minutes of the second period.
General Manager Paul Holmgren said Carcillo, who reportedly has a knee injury, has not been ruled out and that "he's made progress" since being injured Friday. Holmgren nodded when asked if Carcillo could play, but did not reveal the nature of the injury.
"We're taking a lot of extra guys," Holmgren said. "If we need somebody to go in for a player that might be injured, the coaches have options. I think Michael (Leighton) is an option tomorrow to back up."
"I've been practicing for a week, but that's the first time I've replaced Johan Backlund as the backup in practice," said Leighton, who suffered a high-ankle sprain on March 17. Leighton had the best record of any Flyers' goalie this season, 16-5-2 with a 2.48 goals-against average and .918 save percentage.
Kalinski had 2 assists and was minus-2 in 10 games earlier this season with the Flyers. He had 1 goal and 2 assists in 12 games the season before. Kalinski spent most of this season with the AHL Adirondack Phantoms where he had 10 goals and 28 points and was minus-8 in 69 games.
Holmgren said he expects Kalinski, if he gets in the lineup, to play a grinding style of game.
"He didn't get quite the opportunity this year with the Flyers that he got last year," Holmgren said "He's a funny kid because when he's in the American League, he's expected to produce points and when he comes up here the role he's in is more of an energy guy and to be more of a checker. I think that's what we project him to be when he makes it to the NHL and if he plays a game in the near future, that's probably the role he'll be in."
Kalinski suffered a rare injury, compartment syndrome, on Jan. 3, 2009, when he was knee-checked and his thigh muscle swelled dramatically, cutting off the flow of blood to his lower leg. He underwent major surgery and amazed doctors with his quick recovery, leaving the hospital in 10 days and returning to play in six weeks. The outcome was so dramatic a local hospital uses his case to promote its surgery unit in a commercial that regularly airs on Flyers' broadcasts.
"That was a very scary thing for Jon to go through and to come back in the time he did from that is incredible," Holmgren said.
Power outage -- The Flyers know they have to improve their work on the power play against the Bruins. The Flyers were the NHL's third-best power-play team, with a 21.4 percent success rate, during the regular season, but they are 0-for-10 in the past three games and only 2-for-15 for the series.
The Bruins killed all 19 Buffalo Sabres' power plays in their Eastern Conference Quarterfinal series and lead the playoffs with a 94.1 percent kill rate.
"I don't think our execution has been really good," said Dannny Briere, who tied for third on the Flyers during the regular season with 8 power-play goals. "The biggest problem we have is coming up the ice, which is something I can't understand with the players that we have. We're not in sync, we're not coming together as a group. We're all trying to do it alone. That's an area we have to get better in. It's not really something that they do well, it's us not being in sync and it's us not doing it right, right now."
Flyers coach Peter Laviolette said the team has been hurt by its inability to get into the zone and set up its power play.
"(Briere's) right. The initial set up on the power play hasn't been very good for us," Laviolette said. "A lot of times, (we haven't been good at) those one-on-one battles for the puck and making sure that we get a second man in there in support before they do. He's right. There was a lot of turnover. We either got the puck in or we got it deep and there was some sort of battle and the puck squirted out and we didn't have a man close enough or we didn't win those one-on-one battles. He's right. There were some times when it was one-and-done, we may have gotten a chance, but it was one-and-done and we didn't have sustained offensive-zone time on those power plays. I think that's an accurate statement."
