He has captured several wins against notable fighters, including Alfred Cole, Michael Grant, Lance Whitaker, Shannon Briggs, Charles Shufford, Cedric Boswell, but has been unable to replicate these performances in title fight situations, although the loss to Chris Byrd was by only one point in a very controversial split decision.
