For nearly four years, UFC middleweight champion Anderson Silva has ruled the 185-pound weight class with an iron fist. On August 7th, at the Oracle Arena in Oakland, California, he will look to add to his record six title defenses when he takes on the one man brash enough to call him out, number one contender Chael Sonnen. This championship bout, which is the main event of UFC 117: SILVA vs. SONNEN presented by Tequila Cazadores, headlines the first UFC event in Oakland.

UFC 117 also features former Ultimate Fighting Championship welterweight champion and recent inductee into the UFC Hall of Fame Matt Hughes against 170-pound contender Ricardo "Big Dog" Almeida, and an explosive lightweight bout pitting Clay "The Carpenter" Guida against Rafael dos Anjos.

"When we offered Chael Sonnen this shot at the title, he promised us one thing: that he was going to make this a fight," said UFC President Dana White. "I know he means it, and after beating three legit contenders in Nate Marquardt, Yushin Okami, and Dan Miller, he's definitely going to bring the best out of Anderson Silva on August 7th. And as far as Anderson is concerned, he wants to remind everybody why he's considered the best pound-for-pound fighter in the world."

"We are very excited about this event coming to Oakland and have been receiving many inquiries about the match," said Mark Kaufman, SMG's GM at Oracle Arena. "We anticipate seeing many more fights in years to come."

Undefeated in the UFC and one of the most dominant champions to ever grace the Octagon, Anderson "The Spider" Silva (fighting out of Curitiba, Brazil / professional record - 26-4) made his sixth successful title defense against Demian Maia at UFC 112, a streak that dates back to July of 2007. Known for his striking abilities, Silva is also a Brazilian jiu-jitsu black belt under the world-renowned Nogueira brothers and a dynamic fighter who can do it all in the Octagon. His length often causes problems for his opponents, as only two of his last 11 victories have gone to the scorecards. But the champion now faces a fighter that believes he has figured out a way to stop The Spider.

"Chael is a very good fighter," Silva said. "I am training very hard with my team, and Minotauro Nogueira and Lyoto Machida, and I will be ready. This is a title fight and I expect him to be ready because I know I will...
