The rematch proved unable to live up to the original, as Arguello seemed spent and as if he did not have his heart in the fight. Pryor won by a 10th-round knockout, and both fighters retired following the bout. Both would later come out of retirement, both men being driven by financial problems and cocaine addictions. Both enjoyed a fair amount of success in doing so, perhaps most famously when Arguello knocked out former champion Billy Costello in four rounds. Pryor was also largely successful in his comebacks, although he would suffer the only loss of his career in one of them. Eventually, it was discovered during a medical test that Pryor had significantly lost vision in one of his eyes, and after that he was denied a boxing license.
