I know what is going to happen.
The fight will be confirmed. A week from the fight Cyborg will get injured. Chael Sonnen will step up to fight Ronda but Ronda wont take the fight.
All her fans will hate her. the end.
Chael is pretty good at cutting weight. If he can get to 135 they can fight unsanctioned in Brazil before he goes to Anderson's barbecue!
Ronda's an unofficial member of the scrap pack, she'd be down
Not to mention Sonnen's well documented BJJ holes and Ronda's deadly armbar!
