Durán later fought for the World Middleweight Championship, meeting Marvelous Marvin Hagler in Las Vegas on November 10, 1983. During the fight, Duran broke his hand and lost in a very competitive fight that went the full fifteen rounds. After 13 rounds, two of the judges had Durán one point ahead, and the other judge had it even. Hagler fought tenaciously to win the final two rounds and get a unanimous decision victory. The judges' scores were 144–142, 144–143, and 146–145. Despite the loss, Durán became the second man to take Hagler to a fifteen-round decision (Vito Antuofermo was the other) and the only one to do so while Hagler was the world champion.
