UFC president Dana White broke the news with Fox Sports on Monday. "TUF Brazil" is scheduled to hold tryouts for competitors next month. The two coaches, as has historically been the case, will square off at the conclusion of the season.
Sonnen (28-13-1), who coached the U.S. version of the show last year opposite light heavyweight champion Jon Jones, is scheduled to fight Rashad Evans at UFC 167 next month in Las Vegas. That fight will remain intact.
A former No. 1 contender at middleweight and light heavyweight, Sonnen, 36, fought for a UFC title three times in the span of a little more than three years. He has made a habit of publicly calling out opponents, recently setting his sights on Silva.
Silva (35-12-1) fought just once in 2013 -- a second-round knockout win over Brian Stann at a UFC on Fuel event in March.
A veteran of professional mixed martial arts since 1996, Silva has rallied to a 2-1 record in his past three fights after a 27-second knockout loss to Chris Leben in 2011 prompted calls for his retirement.
Silva coached on the inaugural season of "TUF Brazil" opposite Vitor Belfort last year. The two never met in what would have been a rematch of their first fight in 1998, due to an injury to Belfort.
No details were announced regarding a date or venue for the Sonnen-Silva fight. It most likely will be contested at 205 pounds.
The U.S. version of "The Ultimate Fighter" first aired in 2005. It will feature female coaches and fighters for the first time.
