Henderson’s message is a familiar chant from his Federal Way alma mater. A former Decatur High School wrestling standout, Korean American Henderson won the World Extreme Cagefighting (WEC) interim light heavyweight title on Oct. 10 in San Antonio, Texas. WEC is owned by the Ultimate Fight Championship (UFC). With only three years of experience in Mixed Martial Arts (MMA), the 25-year-old is heading to the top.
