Sonnen and Silva have been embroiled in a war of words for much of 2013, which led to the Brazilian angrily confronting his nemesis at a Las Vegas convention last month.
White dropped a bombshell on Sonnen as he was interviewed by the two-time title challenger this evening by revealing that he will coach his opponent Silva in Brazil before fighting his long-time foe next year.
On FOX Sports he said: "People in my own company will be mad at me for this but I guess I can give you something.
"I told everyone we wouldn't release the coaches for TUF Brazil until mid-November, but I guess we'll do it here.
"The coaches are Wanderlei Silva and Chael Sonnen. Then those two will fight. You will have a ton of security down in Brazil and it should be a fun season."
Both men have served as coaches on the popular reality-based format previously, with Silva appearing on the programme's inaugural series in Brazil last year.
Before Sonnen's attention can turn to Wanderlei, he has a light-heavyweight showdown booked for November 16 when he takes on former champion Rashad Evans at UFC 167.
