Five months after losing the welterweight championship to Roberto Duran in a unanimous decision, Sugar Ray Leonard regains the title by getting Duran to cry out “No Mas!” Roberto Duran had returned to Panama a hero after winning the first fight in Montreal but came into the second fight at the Louisiana Superdome out of shape. Leonard focused after losing dominated the fight as Duran, tired and hurt, yelled “No Mas!” in the eighth round, ending the fight.
