PHILADELPHIA -- Flyers coach Peter Laviolette would not comment on any possible lineup changes with forward Ian Laperriere cleared to play.

Still, it would be a shock to see Laperriere in the lineup Tuesday night as he tries to return from a concussion and brain contusion after taking a shot to his face in Game 5 of the Flyers' first-round series against New Jersey. Jeff Carter, meanwhile, remains a long shot to return from a broken foot in this series.

It would not be a shock to see big defenseman Ryan O'Byrne back in the lineup for Montreal and it's possible erstwhile forward Sergei Kostitsyn could return for the first time since Game 5 of the first-round series against Washington.

O'Byrne would give the Canadiens more size on the back end. It's likely defenseman Marc-Andre Bergeron would be limited to power-play time, moving to a reserve forward spot. Mathieu Darche and Benoit Pouliot (two assists in 15 games) could be candidates to come out of the lineup if O'Byrne and Kostitsyn return.

Leino finally delivering for Flyers

One player who has come out of nowhere to have an impact on the Flyers' playoff fortunes is former Detroit forward Ville Leino. The native of Savonlinna, Finland, was traded to the Flyers before the Olympics as the Wings looked to move some salary and make room for players returning from injury. When he arrived in Philadelphia, the Flyers were playing well and he ended up being a healthy scratch for much of the last part of the regular season.

"Sometimes the questions come up about a player and they're not playing well or they're not getting minutes or they're not in the lineup," Flyers coach Peter Laviolette said Tuesday morning. "A lot of times it has nothing to do with a reflection of that player. Our team was playing really well for a long period of time."

When Leino finally got a chance in the postseason, he has delivered two goals and seven assists in nine postseason games. He has four multi-point games.

"We were healthy up front for awhile, then the injuries started to happen and Ville got his chance and his opportunity," Laviolette said. "I think he's gained a lot of confidence as he's played more games, confidence with his teammates, with his line certainly, with me, and he's done a really good job. He's been an excellent hockey player for us in the playoffs."

Leino acknowledged the trade caught him by surprise.

"It was a shock, obviously. It's fast," he said. "You know there might be something, something might be happening. Until it happens, you never know what's going on. It's a shock for sure. Obviously, you feel a little disappointed for maybe not being good enough or whatever reason you got traded."

Then he had to be patient while he waited for his opportunity to contribute here.

"After I started thinking [about] it positively, it was a good change," he said. "People are really nice here and it's been a great time even though it was a tough start here for six games or seven games or whatever I didn't play. I just had to kind to wait my turn, almost to the playoffs. This is my biggest chance and biggest way to contribute right now."

Mike Cammalleri, limited to one shot in Game 1, said people seem to be underestimating the Flyers' skill set.

He pointed to veteran defenseman Chris Pronger as a guy who gets all kinds of attention for being physical, but who brings a lot more to the table.

"I think he's much more of a skilled player than people are giving him credit for," Cammalleri said. "I think they snapped it around on us pretty good last game and we weren't very good. But it's their skill you've got to worry about. You're going to play physical games in the playoffs. It is what it is. That's fun; it's fun to get hit and be hit and play contact hockey."

When it came to discussing Pronger's game and whether it's evolved as the defenseman has gotten older, Cammalleri declined to comment.

"I'm not going to talk in detail about his game," he said. "Ask me after the series."

He then joked he was happy now to talk about how good Washington defenseman John Carlson was in the opening round.

"You guys can ask me about that Carlson kid all you want now," Cammalleri joked. "I'll tell you, yeah, I was so impressed by him. I think he's a great player, I think he's going to be a stud, but I wasn't going to tell him that during the playoffs."
