He was a two-time All-State wrestler at Corona del Sol High School in Tempe, Arizona, before going on to wrestle at Pima Community College, where he was a NJCAA All-American.
Despite Shamrock's belief that Forbes was a force to be reckoned with, he lost his preliminary fight against Noah Inhofer via submission.
He was brought back on the show after Inhofer asked to be sent home (therefore disqualifying him from the competition) for fear that his girlfriend believed he had cheated on her.
Forbes lost again in his just received semi-final spot to Josh Haynes via guillotine choke despite dominating the first round that even Ortiz admitted could have been scored 10-8.
In his first fight since leaving the UFC, Forbes fought Strikeforce veteran Anthony Smith at Crowbar MMA: Fall Brawl on September 11, 2010.
