Holmes returned to the ring in 1991 and became a much more active fighter, usually fighting on "USA Tuesday Night Fights" cards every few weeks against up and comers and journeymen. After five straight wins, he fought Ray Mercer, the undefeated 1988 Olympic Gold Medalist, on February 7, 1992. Holmes pulled off the upset and won by a 12-round unanimous decision. (Holmes later claimed that he fought Mercer in spite of having a detached retina.) The win got Holmes a shot at Evander Holyfield for the Undisputed World Heavyweight Championship. On June 19, 1992, Holyfield defeated Holmes by a twelve-round unanimous decision.
