Matt Hughes and Renzo Gracie will square off – four years after meeting inside the Octagon.

Gracie confirmed with that he will meet Hughes in a super-fight at the ADCC Submission Wrestling World Championship next year in September.

“It’s a done deal,” Gracie said. “Matt asked to compete again at the ADCC and they offered me this wonderful fight. I wasn’t expecting for this, but I immediately accepted it.”

Gracie won the 1998 and 2000 ADCC gold medals, while Hughes competed in the tournament before. Hughes won the MMA fight in Abu Dhabi in 2010, scoring a third round TKO victory.

“Every time I have a chance to compete, I’m in,” Gracie remarked. “I can’t say no. He fought there before, he’s really tough. It’s going to be a great fight.”

Hughes’ ADCC experience includes wins over Ricardo Almeida and Jeremy Horn, while he lost to Jeff Monson and Tito Ortiz.
