Two MMA legends are set to collide once again, but they will do it outside of the Octagon.

Matt Hughes and Renzo Gracie, who fought at the UFC 112 card in Abu Dhabi in 2010, will battle in a superfight at ADCC Submission Wrestling World Championship’s next edition, scheduled for September 2015 in Manaus, Brazil.

"It’s a done deal," Gracie told MMAFighting.com. "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 two ADCC gold medals in his career, winning the 1998 and 2000 editions in Abu Dhabi. In his last appearance, he lost a superfight against Ze Mario Sperry by points.

Hughes competed once at the tournament, scoring wins over Ricardo Almeida and Jeremy Horn, and losing to Jeff Monson and Tito Ortiz.

"Let’s do this again," Gracie said. "Every time I have a chance to compete, I’m in. I can’t say now. He fought there before, he’s really tough. It’s going to be a great fight."
