On July 21, 2001 Mosley easily beat IBO World super welterweight champion Adrian Stone (30-3-2, 23 KOs) knocking him out in round 3. The fight took place at Caesars Palace in Las Vegas. Stone moved down to welterweight for the first time in three years to challenge Mosley and was losing the first 2-round before being stopped. Following the win, Mosley said he would like to have a rematch with De La Hoya in a split 50/50 fight or a unification fight against unbeaten Vernon Forrest.
