PHILADELPHIA -- Each team engaged in a bit of gamesmanship in pre-game warm-ups, skating 12 forwards and seven defensemen, leaving lineup questions unanswered.
For the Flyers, the only sure thing is defenseman Nicklas Grossmann will not play. He sustained an upper-body injury in Game 4 and sat out Game 5. He skated Saturday, but apparently wasn't feeling well enough from what teammate Claude Giroux called a concussion to play Sunday.
In Grossmann's place, the Flyers had rookies Erik Gustafsson -- who replaced Grossmann in the Game 5 lineup -- and Brandon Manning out for warm-ups.
The Penguins have dressed seven defensemen and 11 forwards the last two games in the absence of Paul Martin (undisclosed injury), but Joe Vitale skated as the 12th forward, and remains a viable lineup option.
Here is what the lineups could look like when the teams hit the ice for Game 6 of this Eastern Conference Quarterfinal series (Noon ET, NBC, TSN):
Chris Kunitz - Evgeni Malkin - James Neal
Steve Sullivan - Sidney Crosby - Pascal Dupuis
Matt Cooke - Jordan Staal - Tyler Kennedy
Eric Tangradi - Craig Adams
Brooks Orpik - Kris Letang
Matt Niskanen - Zbynek Michalek
Brian Strait - Deryk Engelland
If Penguins coach Dan Bylsma elects to go back to 12 forwards and six defensemen, Joe Vitale would play on the fourth line with Tangradi and Adams.
Scott Hartnell - Claude Giroux - Jaromir Jagr
Brayden Schenn - Danny Briere - Wayne Simmonds
James van Riemsdyk - Matt Read - Jakub Voracek
Maxime Talbot - Sean Couturier - Eric Wellwood
Kimmo Timonen - Braydon Coburn
Matt Carle - Andreas Lilja
Erik Gustafsson - Pavel Kubina
Brandon Manning took pre-game warm-ups, and could potentially replace Gustafsson or Kubina on the third pair. The forward that would come out if Flyers coach Peter Laviolette elected to go with seven defensemen, however, is unknown.
