On a night when Kimbo Slice made his eagerly awaited professional Mixed Martial Arts debut, KJ Noons stole the show with a shocking first-round TKO over heavily-favored Nick Diaz to capture the EliteXC lightweight world championship Saturday. World-ranked Jake Shields earned his ninth win a row with a hard-fought first round submission (rear naked choke) over Mike Pyle, come backing super heavyweight sensation Antonio "Big Foot"Silva won his first fight in nine months via an opening-round submission (rear naked choke) over Jonathan Wiezorek and Kyle Noke, the bodyguard of the late "Crocodile Hunter," Steve Irwin, took his EliteXC debut with a second-round TKO over "Dr." Seth Kleinbeck due to orbital cut. With the exception of Diaz-Noons, which was scheduled for five, 5-minute rounds, the fights were three, 5-minute rounds.
