One of the greatest rivalries in mixed martial arts history will recommence next month.

Former UFC middleweight champion Anderson Silva will face Chael Sonnen in a boxing match June 15 in Brazil, the Spaten Fight Night promotion announced Sunday. Silva, 49, had been teasing his career finale earlier this week, claiming his final fight would take place next month in his birthplace of Sao Paulo.

Sonnen, 47, confirmed his participation via social media.

“Oh Anderson, yoohoo,” Sonnen said. “It’s me again. See you June 15.”

Silva (34-11) and Sonnen (30-17-1) produced one of the most memorable two-fight rivalries in UFC history. Silva was in the midst of a UFC-record 16 consecutive wins when he ran into Sonnen in 2010. The outspoken title challenger from West Linn, Oregon, was a massive underdog going into their first meeting at UFC 117.
