In what might be casually termed a “buzz kill”, UFC middleweight Chael Sonnen has come forward to reveal he hasn’t actually inked a deal to face champion Anderson Silva on June 23 at UFC 147 in a Brazilian soccer stadium or anywhere else for that matter.

Yesterday the UFC announced rivals Sonnen and Silva would meet on the aforementioned date in Rio de Janeiro. The bout is a rematch of their 2010 battle where Sonnen nearly took Silva’s title by way of decision before a last-minute submission by “The Spider” ended things in the fifth frame.

Both Sonnen and his manager, Mike Roberts, confirmed to MMAFighting a bout agreement had yet to be put in place. Sonnen also added he has a “demand” he wants to include in the deal but remained secretive beyond the basic statement.

Sonnen vs. Silva II is easily one of the most anticipated fights in recent years based on the closeness of their first encounter, an even more impressive feat when considering Silva’s dominance inside the Octagon against all other opponents. Adding to the intrigue, Sonnen has also directed an extraordinary amount of trash-talk at Silva, calling him a coward on multiple occasions in addition to numerous other insults both personal and professional.
