The Penguins and Montreal Canadiens seem to agree on this much: Sidney Crosby is the best player in the world.

But move on to just about any other topic -- including who is responsible for Penguins goalie Marc-Andre Fleury being injured late in the second period of a 1-0 victory Tuesday night against the Canadiens at Consol Energy Center -- and their perspectives couldn't be much different.

The Penguins are adamant that Canadiens winger Brian Gionta intentionally knocked Tyler Kennedy of the Penguins into Fleury, causing an unspecified injury that forced Fleury to sit out the third period.

"It's our opinion in here that he shoved [Kennedy]," Penguins left winger Matt Cooke said. "That's what we all thought."

Gionta didn't share that assessment, suggesting that the culprits were Kennedy and gravity.

"If you watch the replay, their own guy falls on Fleury," he said. "Pretty much, it's self-explanatory."

Something that isn't subject to conflicting opinions is that the Penguins (26-8) now own a 13-game winning streak, the second-longest in franchise history, and that they have further distanced themselves from the second-place Canadiens in the Eastern Conference.

That's almost of secondary importance, however, compared to Fleury's health.

The shutout he shared with Tomas Vokoun raised his record to 18-5 and losing him for an extended period would be a serious blow.

"If your No. 1 goalie ever gets hurt, you worry about it," left winger Chris Kunitz said. "He's a huge part of our team."

Coach Dan Bylsma offered no information on the nature or severity of Fleury's injury -- preliminary indications were that it might be a neck problem -- but teammate Kris Letang put forth an optimistic evaluation of Fleury's prognosis.

"I think [Fleury] will be all right," he said.
