I've heard a few names being tossed around
Apparently Vitor Belfort has said he'll take a fight against Fedor and it's on the Wiki entry for what that's worth.
The other name I heard was Fabricio Werdum since his fight with Overeem was cancelled assuming Strikeforce would let him fight for Affliction (actually they could use it as good advertising for the Gina/Cyborg card)
Funniest suggestion...
Seth Petruzelli! He killed Elite XC! Maybe he can kill Affliction too!
