After weeks of speculation, the planned May encounter between Chael Sonnen and Wanderlei Silva is now official.

The two Ultimate Fighter: Brazil coaches will square off on May 31 at UFC Fight Night from Brazil. Officials made the announcement during Sunday’s post-fight press conference.

Sonnen has been calling out Silva for years, dating back to his first fight with then-UFC middleweight champion Anderson Silva.

UFC officials finally paired the two rivals up for the third installment of TUF: Brazil, which currently airs on UFC Fight Pass.

The card will feature the finals in the TUF tournament and take place from Sao Paulo’s Ibirapuera Arena.
