The Penguins' goaltending rotation — or lack thereof — is starting to take shape. Brad Thiessen was sent back to Wilkes-Barre/Scranton on Thursday after taking part in the morning skate. Brent Johnson, following a monthlong knee problem, has returned as Marc-Andre Fleury's backup and might play Friday night in Buffalo.

Fleury, who has participated in 64 games, said he is not fatigued and would be willing to play in every game remaining in the regular season.

"I feel good now," Fleury said. "So I just go one day at a time, one game at a time. I don't think too far ahead."

Bylsma said he has confidence in Johnson and his balky knee.

"He wouldn't be backing up if he wasn't able to play," Bylsma said.
