From backyard brawler to YouTube sensation to mixed martial artist and now professional boxer, Kevin "Kimbo Slice" Ferguson made a successful heavyweight debut, scoring a 10-second first round knockout over James Wade at the Buffalo Run Casino in Miami, Oklahoma. The fight never even got a chance to really get started as Kimbo came out fast looking to make it an early night.

Although his movement appeared to be hampered due to an injured right leg that was wrapped around the thigh, Kimbo immediately charged forward, landing two right hands that rocked Wade before a devastating uppercut crumpled him to the canvas. While it's clear that there's still a lot of room for improvement, there's no denying that Kimbo can still electrify a crowd, as evidenced by the excitement from the fans in the video below. Check out his performance and let us know what you think.
