At its inception, the event was to take place at an 80,000 seat soccer stadium in Rio de Janeiro and would feature the long-awaited rematch between UFC middleweight champion Anderson Silva and his great foil Chael Sonnen.
Complications from a United Nations conference scheduled for Rio around the same time then saw Silva-Sonnen 2 moved to UFC 148 in Las Vegas and the rematch between Wanderlei Silva and Vitor Belfort bumped up to the UFC 147 main event slot; the event itself was moved to the smaller Mineirinho Arena in Belo Horizonte.
When Belfort broke his hand and was forced out of the bout, Rich Franklin was brought in to rematch Silva at a catchweight (the two first met in 2009 in a catchweight fight, with Silva losing a unanimous decision). Now, the bout will see Silva-Franklin 2 at the top of the card, with heavyweights Fabricio Werdum and Mike Russow supporting in the co-main event.
The main card lineup will see the two finals matches of The Ultimate Fighter: Brazil — which will take place in the featherweight and middleweight divisions — as well as two matches featuring UFC debutants Hacran Dias and Miltinho Vieira taking on two-time Octagon vets Yuri Alcantara and Felipe Arantes, respectively.
The preliminary card will feature exclusively match ups between competitors from TUF: Brazil. Despite the greatly altered lineup, this card is still being marketed as a pay-per-view event.
