Jeffries had not fought since retiring in 1905 and spent much of his time running his farm, where his weight reportedly climbed above 300 pounds and may have reached more than 330 pounds. By the time he agreed to challenge Johnson, the former champion faced the enormous task of shedding well over 100 pounds before entering the ring at approximately 227 pounds.

The dramatic weight loss, combined with six years away from competition, left many questioning whether Jeffries could truly return as the fighter who had once dominated the heavyweight division. Johnson answered that question emphatically.

Johnson dictated the terms from the opening stages. He repeatedly made Jeffries miss, answered with quick counters, and tied up the former champion whenever he tried to fight at close range. Jeffries was never able to establish the grinding style that had served him so well during his title reign.

The longer the fight continued, the wider the gap became. Johnson looked comfortable, picked his punches and forced Jeffries to work far harder than he wanted, while the former champion’s movement and offense steadily faded.

The champion repeatedly landed clean punches, dictated the pace and steadily wore down the challenger, whose comeback never gained momentum.

Johnson finally ended matters in the 15th round, knocking Jeffries down three times before Jeffries’ corner threw in the towel to save him from further punishment. The stoppage handed Jeffries the lone defeat of his professional career while Johnson successfully defended the heavyweight championship.

The championship had consequences well beyond the sport, as the outcome triggered unrest in multiple cities and cemented the bout as one of the most historically significant events boxing has ever produced.

The bout later prompted censorship of the official fight film and remains one of the defining events in both boxing history and American history.

More than a century later, Johnson’s dominant performance still stands as one of the clearest examples of an elite heavyweight champion completely outclassing a legendary former titleholder who attempted one comeback too many.
