There were only two competitors in this class. Oliver Kirk won the title by defeating George Finnegan by a TKO in round three. Kirk holds a special place in Olympic boxing history as he also won the title in the featherweight class, the only Olympic boxer ever to win two gold medals at one Olympics. Finnegan also competed as a flyweight, winning the gold medal in that class. Jerry Casey was the 1904 AAU Champion, and he was entered in this class, but did not compete.
