Justin “The Insane One” McCully (8-3-2) 6’2”/240 lbs., fights out of Huntington Beach, Calif. After his dominant three round victory over Antoni Hardonk in April of 2007, bright things were forecast for heavyweight McCully. Then injuries sidelined the Brazilian Jiu-Jitsu Black Belt for much of the year. Now healthy and eager to assault the heavyweight division, “The Insane One” returns to the Octagon™ against Gabriel “Napao” Gonzaga (8-3-0) 6’1”/240 lbs. Gabriel Gonzaga’s rise up the heavyweight ranks was nothing short of spectacular, with wins over Kevin Jordan, Fabiano Scherner, Carmelo Marrero, and Mirko Cro Cop thrilling fight fans around the world. Losses to Randy Couture and Fabricio Werdum have slowed the Brazilian’s progress, but after an intense training camp in his adopted home of Ludlow, he is ready to once again regain his spot in the UFC title picture.

Cole Miller (13-3-0) 6’1”/155 lbs., fighting out of Coconut Creek, Fla., notched impressive wins over Andy Wang and Leonard Garcia after his stay on The Ultimate Fighter® 5, furthering his reputation as one of the lightweight division’s top up and comers. Though the Georgia native hit a bump in the road in a hard fought January loss to Jeremy Stephens, this Brazilian Jiu-Jitsu purple belt is more focused than ever heading into his match-up with Jorge Gurgel (16-3-0) 5’9”/155 lbs. Winner of three of his five UFC fights, Jorge Gurgel’s energetic style has made him a fan favorite around the world. It wasn’t until his hard-fought decision win over John Halverson at UFC 82 in March that fans got to see the real “JG,” as he used all his talents to earn his most impressive victory yet in the Octagon. The Cincinnati fighter will look to build on his success against Miller.
