The UFC officially announced on Monday that Anderson Silva vs. Chael Sonnen 2 will take place June 23 in Rio de Janeiro. However, according to Sonnen, nothing is official just yet.



"My demand has not been met," Sonnen told MMAFighting.com when asked for a comment on the rematch. "I've signed nothing."



Sonnen's manager Mike Roberts also confirmed that Sonnen has yet to sign a bout agreement, but it appears as though that is just a formality at this point.



As for what his demand is, Sonnen only said, "it's coming."



UFC 147 is scheduled to take place at Rio de Janeiro's Estádio Olímpico João Havelange, and according to UFC president Dana White, the venue will seat approximately 80,000 people for the highly-anticipated rematch.

That is, of course, if Sonnen decides to sign the bout agreement.
