NEW YORK — Adrenaline MMA announced today that heavyweight stars Tim Sylvia and Ben Rothwell have signed multi-fight contracts with the newly-formed promotion. Sylvia (24-4) is a former 2-time UFC heavyweight champion, while Rothwell (31-5) was undefeated in the IFL for the champion Quad Cities Silverbacks. Sylvia, 6-foot-8 and 265 pounds, has fought 13 times in the UFC and defeated top performers like Jeff Monson, Andre Arlovski (twice), Brandon Vera, Ricco Rodriguez and Assuerio Silva. “Adrenaline is a new promotion, but it allows fighters to fight for other organizations… that’s huge,” Sylvia said. “I’ve got 3 to 4 years left and want to fight as much as possible, so this is the perfect choice for me at this time.” Rothwell, 6-5 and 265, has won 13 straight bouts, including all 9 of his IFL fights. “Adrenaline will give me the chance to take things to the next level,” Rothwell said. “I’m ready to see how I fare against the best heavyweights in the world.” Sylvia and Rothwell both train at Miletich Fighting Systems in Bettendorf, Iowa.
