PHILADELPHIA -- Penguins coach Dan Bylsma announced after the morning skate Wednesday that defenseman Paul Martin will not play in Game 4 against the Flyers because of an undisclosed injury.
Bylsma said the rest of the Penguins lineup will be a game-time decision, but he referred to rookie defenseman Simon Despres as having an opportunity Wednesday night.
"I think you're going to see Simon step up in a big way," Bylsma said.
Zbynek Michalek also did not skate Wednesday morning, but there was no reason given for that and his status for Game 4 is up in the air. If he can't play, Brian Strait will be in the lineup. He has been a healthy scratch for the first three games.
Dustin Jeffrey, Eric Tangradi and Joe Vitale all will likely play for suspended players James Neal, Arron Asham and Craig Adams. Vitale played in Games 1 and 2 before being benched for Game 3 in favor of Richard Park. Tangradi played one game in the playoffs last season while Jeffrey will be making his playoff debut.
In the regular season, Jeffrey had six points in 26 games and Tangradi had two points in 24 games. Despres had four points in 18 games.
"It's guys that have played for us and been in roles for us," Bylsma said. "It's a big game, obviously a huge game for them to get dropped into, but they know exactly what to do and what is expected, where they fit in and they've done that for us before."
Here is what the Penguins forward lines looked like in the morning skate:
Steve Sullivan - Sidney Crosby - Pascal Dupuis
Chris Kunitz - Evgeni Malkin - Tyler Kennedy
Eric Tangradi - Jordan Staal - Matt Cooke
Dustin Jeffrey - Joe Vitale - Richard Park
The Penguins rotated their defensemen and since it is unclear if Michalek will play it's too difficult to determine the pairings.
Marc-Andre Fleury will get the start in net after being pulled following the second period of Game 3. Fleury has allowed 17 goals on 84 shots in this series and has a 6.34 goals-against average and .798 save percentage.
