There’s no question the upcoming rematch between UFC middleweight champ Anderson Silva and rival Chael Sonnen sells itself and would fill an arena in any MMA-loving area. However, when the bout was revealed for UFC 147, the prospect of seeing the two face off with the backdrop of 80,000 fans in Silva’s proverbial backyard of Rio de Janeiro was one no fan could resist salivating over.

Unfortunately, it now appears the match-up may be in jeopardy, at least in terms of taking place in a Brazilian soccer stadium.

Last week it was reported a United Nations conference scheduled in the days preceding UFC 147 would prohibit the event from taking place based on Rio’s inability to coordinate two major events during the same period of time. While talk initially pointed to the show simply being moved back a week or two, Brazilian media outlet O Globo has revealed Silva-Sonnen is not only switching dates but countries as well.

According to the report, the fight will now take place in Las Vegas with June still being targeted. UFC President Dana White, Silva, and Sonnen are all expected to be in Brazil on Tuesday to address the situation at a press conference where more details will likely come to light.
