Tyson Griffin

Griffin was a standout wrestler at Albany High School and moved on to wrestle at Skyline Junior College before dropping out. He began training at David Terrell's NorCal Fighting Alliance and the Cesar Gracie Academy. During his first mixed martial arts training session, Terrell cut two gashes over Griffin's left eye, requiring stitches. Griffin states that he committed himself to a career in MMA while in the hospital waiting room. His mother supported him during his first year of training, but after his professional debut he had to get side jobs to support himself through his early career.

Tyson Griffin began his professional career in 2004 in the Gladiator Challenge promotion. In his third bout, he dropped to featherweight to earn a TKO victory over future World Extreme Cagefighting featherweight champion Urijah Faber, which stood as Faber's only defeat for over three years. Griffin went on to win all of his first six fights before facing Duane Ludwig at Strikeforce: Revenge. He won the bout by TKO in the first round, attracting the attention of major promotions. After considering offers from Pride Fighting Championship and the UFC, Griffin signed with the UFC so that he could continue to fight stateside. While cornering for David Terrel at UFC 59 in Las Vegas, Griffin had an opportunity to meet members of the Xtreme Couture camp for the first time.

The back-and-forth bout ended with Edgar trapped in a tight kneebar, but the judges unanimously scored the bout in his favor, handing Griffin his first professional loss. He rebounded with two decision victories over Clay Guida and Thiago Tavares at UFC 72 and UFC 76, respectively. All three of his bouts in 2007 were judged in the top 10 best of year.
