LAS VEGAS – The rematch is happening.

At Saturday night's UFC 143 post-fight press conference, UFC president Dana White confirmed that both UFC middleweight champ Anderson Silva (31-4 MMA, 14-0 UFC) and his nemesis Chael Sonnen (27-11-1 MMA, 6-4 UFC) have verbally agreed to meet in Brazil on an as-yet-undetermined date in June.

Silva was in Las Vegas for Saturday's fight card, and White said an agreement was reached during the event.

Bout agreements are expected to be finalized shortly.

Sonnen, of course, had stated he didn't believe Silva would ever fight him again following the pair's memorable UFC 117 matchup, in which the challenger dominated for four-and-a-half rounds before relenting to the champ. Since that fight, Sonnen has alternated between campaigning for a rematch and dismissing the need for one.

White, however, said the likelihood of the rematch was never in doubt.

"Chael's full of [expletive]," White said. "You guys need to stop listening to Chael."

Silva has remained mostly silent on Sonnen, citing his desire to let the victory speak for itself and his unwillingness to lend any more spotlight to the trashtalking extraordinaire that is his current nemesis.

Earlier this month, White confirmed that Sao Paulo was the most likely Brazilian city to host the June event, which is also expected to feature Vitor Belfort vs. Wanderlei Silva and the final bout of the first-ever "The Ultimate Fighter: Brazil" tournament.

However, White said a venue has yet to be determined.
