The main event for UFC on FS1 on August 17th has been revealed and Chael Sonnen will face former UFC light heavyweight champion Mauricio “Shogun” Rua. 
The fight was announced by Sonnen on Tuesday night’s edition of UFC Tonight on FUEL TV.
“Shogun and I are going to be the main event on FOX Sports 1 on August 17,” Sonnen said. “We were going to fight in Winnipeg, and they pulled it.”
UFC on FS1 #1 takes place on August 17th from the TD Garden in Boston and tickets for the event will go on sale next week.
Sonnen (27-13-1) has lost back to back fights with both of the defeats coming in title fights against Anderson Silva and Jon Jones. Prior to losing his last two fights, he had won five of six fights and included wins over Yushin Okami, Nate Marquardt and Michael Bisping.
Rua (21-7) was scheduled to face Antonio Rogerio Nogueria at UFC 161 next week, but the fight was canceled when Nogueira pulled out of the fight with an injury. He is 3-3 in his last six fights and his last win came at UFC on FOX 4 last year against Brandon Vera.
