Dana White hints about Sonnen vs. Silva location

Dana White at the press conference in Calgary today when talking about the Anderson Silva vs. Chael Sonnen fight said it would be held in an 80,000-seat stadium in Rio de Janeiro.

Originally the idea was to hold the fight in Sao Paulo.  The delay in the location being officially announced was a noise ordinance in Sao Paulo that would have prevented the event taking place during what is the normal U.S. PPV time. 

Who would you have the most interest in for Fabricio Werdum's next title defense?
