The showdown at the Convention Hall in Atlantic City was billed as “Once and For All,” and it lived up to its name. Tyson entered the ring with the WBA, WBC and IBF heavyweight titles, while Spinks remained the lineal and Ring Magazine champion having never lost his heavyweight crown inside the ring. Both men were undefeated, making it one of the most anticipated heavyweight title fights of its era.
Negotiations dragged on for months before an agreement was finally reached, producing at the time the richest fight in boxing history. Tyson reportedly earned about $22 million, while Spinks received $13.5 million as fans packed Atlantic City’s convention hall and hundreds of thousands bought the match on pay-per-view.
There was late drama before the opening bell when Spinks’ manager Butch Lewis challenged Tyson’s gloves, forcing officials to inspect them and briefly delaying the fight. Rather than disrupting Tyson’s focus, the incident seemed to strengthen it.
As soon as referee Frank Cappuccino signaled the start, Tyson exploded forward. Less than 10 seconds into the contest, he landed a crushing left hook that immediately backed up Spinks. The former light heavyweight champion tried to clinch, but Tyson relentlessly cut off the ring and continued to unload power punches.
About a minute into the round, Tyson drilled Spinks with a left uppercut and a right hand to the body, sending him to the canvas for the first official knockdown of his professional career. Spinks beat the score, but he was still badly shaken. Moments later, Tyson slipped a right hand, answered with a thunderous left hook and a sweeping right hand, knocking Spinks down again. This time there would be no recovery. Cappuccino counted him out at 1:31 of the opening round.
Only ten punches landed during the entire fight, eight by Tyson and two by Spinks. The explosive finish became the defining image of Tyson’s prime and is still considered by many to be the pinnacle of his remarkable career. Spinks retired after suffering the only loss of his professional career, while Tyson’s 91-second knockout became the defining performance of his championship reign.
