Through seven and-a-half rounds at the Louisiana Superdome on Nov. 25, 1980, Roberto Duran and Sugar Ray Leonard had participated in what most people would describe as a nondescript return engagement.
Neither fighter had been hurt, and, though Leonard clearly had established an advantage by outboxing and even mocking Duran, the outcome was still very much in doubt. Compared to their original showdown - the epic "Brawl in Montreal" five months prior that Duran won by decision - "The Rematch" had been something of a dud.
Then, it happened.
After an exchange and a clinch, Duran suddenly waved his hands in disgust and walked away from Leonard in round eight. Confused, referee Octavio Meyran ordered the fight to resume, and Leonard landed a body shot. But Duran walked away again, and then uttered a phrase that has become a sports lexicon staple.
Emmy Award-winning director Eric Drath - known to fight fans for his heart-wrenching "Assault in the Ring" - chronicles the events surrounding Duran's stunning surrender in the ESPN "30 for 30" series (6 p.m., Tuesday, ESPN). The film reunites both fighters in an attempt to achieve final closure for two of the most legendary figures in boxing history.
Drath takes viewers behind the scenes to try and figure out what really happened to Duran, regarded as perhaps the greatest lightweight in boxing history and one of the top fighters to ever lace on the gloves.
Even Duran's late, great trainer, Ray Arcel, was dumbfounded by his fighter's actions.
Immediately after the debacle, Duran claimed stomach cramps. Which, considering the amount of food Duran inhaled in the hours after the weigh-in, was at least believable.
Duran reportedly consumed a mountain of steaks and drink after killing himself to make the 147-pound weight limit. In the months after the unanimous decision over Leonard on June 20, 1980, Duran partied hard. It was Leonard's brilliant plan to get Duran right back in the ring quickly, knowing "Manos de Peidra" would likely be unprepared and out-of-shape.
However, most boxing experts think Duran was simply humiliated by Leonard's taunting tactics in round seven. Leonard - continuously insulted before the first fight and bullied once in the ring - exacted revenge by making fun of Duran in the rematch.
In the most famous sequence, Leonard wound up with a telegraphed right-hand bolo punch that diverted Duran's attention just enough to pop him with a left jab that watered Duran's eyes.
Roberto Duran - one of the most ferocious beasts in boxing history - was being reduced to a punch line. And so, most people think he just gave up - to limit further embarrassment.
Even 33 years later, the sight of Duran quitting in the middle of a gigantic fight is shocking.
Despite his incredible comebacks in the years after "No Mas" - he went on to win titles in two more weight divisions - there are those who have never forgiven Duran for his surrender. Even before their third fight in 1989 - "Uno Mas" which Leonard won by decision - Duran offered little in terms of explanation.
Now 62, the great Panamanian will offer his side of the story.
Leonard, meanwhile, claimed he was never given his just due for making Duran quit.
