Undefeated for eight years at 155 pounds -  BJ Penn takes on the UFC season one winner Diego Sanchez in the main event of the UFC 107 at the FEDEX forum, Memphis, TN.

Sanchez started his pursuit of honing his fighting prowess when he was 9. “I started karate lessons at nine years old. Years of martial arts training aided my athletic pursuits at Del Norte High School as a wrestler and on the high school gridiron as a linebacker. In my senior year in 2000, I won the state championship in the 152 lb weight class and etched my name amongst the best ever grapplers in school history.”

Penn was inspired by a tae kwon do instructor saying, “A tae kwon do instructor moved near my house in 96. He took a few private lessons in jiu-jitsu. I never did tae kwon do. He saw me and my friends hanging out around the neighborhood and asked my father to have them come wrestle with him. I never wanted to go and one day my dad was like if you don’t go he won’t stop asking me. So I did it to please my dad. When I went there he tapped me out and my mind started rolling and never stopped.”
