"I'm trying to recover in order to be fit to fight at UFC Rio. The biggest event of martial arts is coming back to Brazil after 14 years and I'll be there, strong and ready. Anderson Silva will be the main even against Yushin Okami and I want to be the co-main event"
Nogueira has previously expressed interest in rematching Mirko "Cro Cop" Filipovic but UFC president Dana White said Mirko would never fight in the UFC again following his KO loss to Brendan Schaub. Still, Nogueira doesn't present a huge KO risk and the bout would also represent a rematch of one of the greatest fights in MMA history. Personally, I'd be more excited for that fight than just about any other irrelevant heavyweight fight in the sport.
The GracieMag post also mentions Schaub as a possible opponent for Nogueira.
