i read that once. It was some "expert" that speculated it. Personally, i dont think so, but i cannot say for sure that it was not so. Afterall, Duran did claim(among other excuses) that he was having stomach cramps. Might be another way of saying he really needed to go?? but again, not likely.
Will try to find the original quote, and link it
found it!
it was trainer and commentator Gil Clancy that speculated that perhaps Duran qiut cause he needed to go..
Their rematch was held in New Orleans on November 25, 1980. This time around, Leonard used far more lateral movement and jabs, staying off the ropes whenever possible. In round 7, Leonard taunted Duran, dropping his arms and winding up with a bolo punch. Neither fighter had absorbed much punishment, but Leonard had a narrow lead on all three scorecards after 7 rounds. In round 8, Duran turned around, walked to his corner and gave up. Although Duran is widely remembered for the now famous words, "no más," he never actually said them. It was actually commentator Howard Cosell who uttered the phrase, which inspired an angry comment from Duran in a 2005 article about the fight (however, the article makes it clear that Duran did quit, as he actually said the Spanish equivalent of "I can't continue"). Regardless, the sports world was stunned by Duran's actions. The controversy regarding this bout and Duran's motivation for quitting continues to this day. However, in an interview with ESPN, Duran had stated that he had started to get stomach cramps and felt it better to quit now than suffer through it. Trainer and TV commentator Gil Clancy opined that perhaps Duran was on the verge of defecating. In an episode of FOX Sports's Beyond The Glory, Duran's trainer said that Duran had turned to him and said "I won't fight anymore with this clown." Duran's manager, Carlos Eleta, said, "Duran didn't quit because of stomach cramps. He quit because he was embarrassed."
