While the details of Fedor Emelianenko’s next fight still remain a mystery, MMA Junkie’s Steven Marrocco is hearing his it could come against Antonio Silva on Dec. 4 .

Fedor Emelianenko (31-2 MMA, 1-1 SF) will in the coming week decide what his immediate future holds in Strikeforce, according to a source close to the fighter.

While speculation on Emelianenko’s next opponent has centered around current heavyweight champion Alistair Overeem or a rematch with Fabricio Werdum, the source said a contest with Antonio “Bigfoot” Silva (14-2 MMA, 1-1 SF) on Dec. 4 is currently on the table for the Russian’s final fight on his current Strikeforce contract.

Strikeforce has yet to determine a city or venue for the Dec. 4 event, and officials could not be reached for comment.

Last week, Scott Coker said Alistair Overeem vs. Antonio Silva was a bout they were looking to book in October, but that would presumably be off the table if a Dec. bout between Fedor and Silva comes together. Overeem doesn’t sound terribly interested anyways. In a recent interview, Overeem mentioned he wants Fabricio Werdum (who is now officially off the shelf until 2011), and if he can’t get him (which he can’t barring an unforeseen turn of events), then he will consider entering the K-1 WGP this fall instead.

No additional word on the 4-6 fight contract extension Fedor and M-1 were talking up last week.

Update: Antonio Silva says he’s currently training for Alistair Overeem under the assumption that that bout is likely, but realizes the fight is not a done deal. He hasn’t been offered a fight against Fedor Emelianenko yet, but he’s definitely open to the possibility.

“Strikeforce hasn’t yet given us a definite opponent, but it seemed likely that it was going to be Overeem, and I’ve been kind of planning accordingly,” Silva told MMAjunkie.com (www.mmajunkie.com) through his manager and interpreter, Alex Davis. “I believe (Strikeforce CEO) Scott Coker has said to a few people that I’m likely to fight Overeem next, and I would be truly honored to fight him for the Strikeforce title.”

“Both Overeem and Fedor are great fighters,” Silva said. “I would be more than happy to fight either one. I have a lot of respect for each of them.”

“For me, there is no pressure,” Silva said. “If I fight the champion, or if I fight the legend, the pressure is on them. Overeem and Fedor do present completely different problems style-wise, so I do hope Strikeforce can determine who it will be – and when – as soon as possible.

“Ultimately, whoever it is, I will be happy to be in the cage and will give it my utmost and fight my heart out. I know that I can beat both Overeem and Fedor, so whatever happens, I guarantee that the fans will see an awesome fight, and I’ll be prepared.”
