Holmes' next fight had the potential to make boxing history. He agreed to terms to fight Michael Spinks, the undisputed champion at light heavyweight, for his twentieth world title defense. A victory for Holmes would have tied Rocky Marciano's mark of 49 consecutive wins without a loss. Spinks, meanwhile, was looking to join Bob Fitzsimmons as the only other boxer at the time to win titles at both light heavyweight and heavyweight. In addition, if he defeated Holmes, Spinks would become the first ever reigning light heavyweight champion to win the heavyweight title.
