Lennox Lewis may not be as big a name as the likes of Mike Tyson, Evander Hollyfield, etc., but that is entirely unfair to him given that he has in the past managed to defeat both of them in a match. One of his most noteworthy matches was against Vitali Klitschko, who lost to Lewis as a result of the match being ended due to Klitschko bleeding profusely.
