According to the penguins.com Dan Byslma said:
Even though it's rumored that Letang suffered a lower body injury and Sykora has been hobbled by a long-running shoulder injury Byslma would say (read: lie)
"The decisions that we made today were not based on injuries."
The interesting angle is Satan. This will be his first game back for Pittsburgh since March 3rd. Even though he's been a disappointment, Satan has still scored 17 goals in the NHL. Also, Satan seemed to turn his game around under Byslma: he scored 3 goals in 7 games for Byslma and was skating noticably harder.
Byslma said today that he still rotate and shuffle players around. So while Satan will take Sykora's place on the 2nd line with Evgeni Malkin and Ruslan Fedotenko, expect to see guys like Pascal Dupuis and Maxime Talbot taking shifts all over the place. And if the Pens have to protect a close lead, that will happen a lot with Craig Adams too.
If Letang can't go, Philippe Boucher, another right handed shot, will take his place in the lineup.
