Yeah I thought Forrest was injured, but man this is an awkward turn of events. Maybe he just sprained his ankle or something, he might be fine now? As for Randy, the only other man he is interested in fighting is Shogun, they might have him fight Rua at Rio if he can recover for it? Randy and Forrest could swap places.
If Forrest takes Randy's place though, they'll almost definitely need someone else to fight Rua. I've wanted to see Forrest vs Machida for a while, but if Machida wins, I hope to God they don't do Rua vs Machida III in Rio -_-.
