In 2002, Tarver defeated former two-weight world champion Reggie Johnson by split decision to win the NABF & USBA light-heavyweight titles, and a guaranteed title shot at Roy Jones. He then scored a fifth round stoppage over Harding in a rematch that was on the undercard of the rematch between Shane Mosely and Vernon Forrest. Tarver was trailing on the scorecards until the 4th round, when he sent Harding to the canvas with a barrage of unanswered power shots; Harding was also floored twice in the 5th round, leading to the stoppage.
