Duran moved up to super middleweight for a third fight with Sugar Ray Leonard in December 1989 (a fight dubbed Uno Más — One More — by promoters), where Leonard's WBC super-middleweight title was on the line, although Leonard's camp insisted that the fight with Durán be at a 162lbs catchweight instead of the 168lbs super-middleweight limit that Durán favoured. In the end, both weighed in below the 160lbs middleweight limit. Durán was uncharacteristically flat for most of what was a strange fight. Although Leonard won the fight by a wide unanimous decision (120–110, 119–109, 116–111), by the end of the fight Leonard looked the worse for wear as he had suffered several bad cuts. Leonard's lip was busted by a headbutt in the fourth round, his left eye was cut in the eleventh round and his right eye was cut in the twelfth round. The cuts required more than 60 stitches. Durán didn't fight again until 1991, so had given up his WBC middleweight crown that he had won against Barkley. Durán seemed to be in decline after the third fight against Leonard, but he persisted and worked his way into title shots for the lesser IBC super-middleweight and middleweight titles in 1994, 1995 and 1996.
