Bloody Elbow, for MMA and UFC news

Always honest, Forrest Griffin tells Sherdog he's anticipating a difficult weight cut and conditioning issues for his upcoming fight in Rio against Mauricio "Shogun" Rua: "I definitely put on more weight than I would like," Griffin told Sherdog.com. "I need to cut weight and it won’t be easy. I’ll have a lot of problems until the fight in Brazil, but I’ve gotta do it. I don’t want to fight at heavyweight, so I gotta cut that f--king weight." "He’s one of the best fighters ever," Griffin said of his opponent, who he submitted in September 2007. "He has a blitz style. He goes forward. He’s dangerous. I gotta make him move backward and let’s see what happens. I want to go hard for all 15 minutes of the fight." "It’s difficult to adjust yourself [to another country]," said Griffin. "There’s the jetlag thing, and it’s difficult to make weight since Brazil doesn’t have the distilled water I use in the U.S. and the food I need to eat. It’s always difficult to change your routine when you go to another country. I feel stupid because I can’t communicate with people from the hotels and can’t even say how I want my eggs. It’s clearly a pain in the ass." UFC 134: Rio coverage

The UFC announced this morning that an injury to Stephan Bonnar has forced him out of his UFC on Versus 5 bout with Karlos Vemola. In Bonnar's place, the UFC has signed Brazilian submission specialist, Ronny Markes (11-1), to face Vemola in August. Markes ranked as the #10 light heavyweight on BloodyElbow.com's world scouting report. The Nova Uniao Kimura team member most recently won a decision against Paulo Filho in April.

Recent cuts by the UFC: Todd Brown (0-2 UFC), Chris Camozzi (2-1 UFC), Rob Kimmons (3-4 UFC), and Dave Branch (2-2 UFC). Camozzi speaking with MMA Junkie: "According to the UFC the issue is less about my performance (they offered to give me a recommendation) and more to do with an overloaded roster and not enough fights for us under contract," Camozzi wrote. "This has nothing to do with the recent merger."
