According to Silva, the fight was offered but Fedor turned it down. He said so in his most recent interview with MMANews.
MMANews.com: People began to take notice of you during your run in K-1 HERO's and there has actually been talk that people feel you are the guy to end the run of arguably the king of MMA right now - Fedor Emelianenko. Were there ever any talks of getting that fight to happen?
Antonio Silva: Yes, there were. We had an offer to fight Fedor in Bodog and actually Fedor was the one who turned it down.
