Previously, the biggest age gap for a professional right was 24 years. "Old Mongoose" Archie Moore suited up for his last professional bout at age 49, taking on 25-year-old "Iron" Mike DiBiase (adoptive father of WWE icon Ted DiBiase) in 1963. It was also DiBiase's last professional fight, as Moore won in a knockout.

Critics have taken aim at Paul since he first laced up his gloves, slamming him as a non-serious fighter and questioning the calibre of his opposition. But as revealed in a three-part Netflix documentary charting his journey to the bout, Paul is laser-focused on silencing naysayers and earning recognition as a bona fide champion.
