VOORHEES, N.J. – The most dangerous obstacle facing the Flyers tonight in Game 5 is not the Devils. In fact, the Devils haven’t presented much of a problem in the last three games.

Instead, the Flyers only have to worry about themselves. Or rather, their enthusiasm.

With the potential of closing out the Eastern Conference finals tonight at First Union Center, the often keyed-up Flyers say they must maintain their composure during the game.

“We have to come in with controlled emotion,” goaltender Brian Boucher said yesterday.

In fact, it was Boucher, a rookie no less, who warned his teammates not to get too excited as his teammates crowded around him after their 3-1 victory in Game 4 Saturday at the Meadowlands.

“Bouchey just said, ‘Relax boys, we haven’t won anything yet’,” said 36-year-old right wing Rick Tocchet. “That put a smile on my face.”

But nothing would bring a bigger smile to the Flyers’ faces than advancing to the Stanley Cup final. Especially since many observers thought that the Devils, who had won four of five meetings against the Flyers this season, were superior heading into the series.

“Everybody thought it would be a cakewalk for the Devils,” Tocchet said, gleaming with satisfaction. “And a lot of guys took it personally.”

Flyers center Daymond Langkow skated with the club yesterday for the first time since suffering a concussion in Game 2. He said he will be examined today by a doctor, but added it is 50-50 as to whether he will play tonight.

“I’m doing pretty good,” said Langkow, who received the concussion on a third period hit by Scott Stevens. “I’m still day-to-day.”

Langkow, who scored the winning goal in Game 2, said he doesn’t remember the incident very well. But after watching it on a replay he said, “It was definitely a clean hit.”

If Langkow returns, Flyers coach Craig Ramsay said he hasn’t decided how to utilize him. As Langkow’s replacement at center, Mark Recchi, who moved over from right wing, has scored a goal in two straight games. Recchi is playing along side John LeClair and Simon Gagne.

Already sporting a half-swollen right eye and a vertical scar of stitches on his nose, LeClair was accidentally struck in the face again by Martin Brodeur’s stickblade in Game 4.

It was Brodeur’s stickblade which accidentally struck LeClair in the face in Game 3, requiring him to receive 36 stitches on his nose and three around his right eye.

Center Eric Lindros (concussion) wll be examined by doctors in Chicago today. If cleared, Lindros could practice with the team Tuesday.
