"I’ve heard on the grapevine from inside sources that he could be injured," said Bisping.

Bisping didn't mention a particular injury but judging from Bisping's subsequent comments, the injury probably isn't a serious one.

“I think the fight will play out similar to when Randy Couture fought Tim Sylvia, but I’m picking Fedor to beat Tim. Tim will give anyone a hard day, he’s a very, very experienced, underrated fighter and has knocked out a who’s who of MMA. But he’s gone a little bit stale lately – he’s trying not to lose as opposed to trying to win which has given him a boring style. In the past he was knocking people out left, right and centre. If he gets back to his roots and goes out like that then who knows, maybe he could surprise a lot of people.”

Update:

A source close to Fedor Emelianenko's camp has informed Fightline.com that Michael Bisping has no inside knowledge on Emelianenko status and that the popular Russian fighter is healthy and ready to fight.
