There were only two entrants in this class, and one of them, [Miles Burke], was over the weight limit for the event but he was still allowed to compete, although the reason is not known. [George Finnegan] won the gold medal by defeating Burke by a TKO in the first round. Finnegan also competed in the bantamweight class, in which there were also only two competitors, but Finnegan lost that title by a TKO in round three against [Oliver Kirk]. The 1904 AAU Champion was J. J. O’Brien who also won that title in 1907, but O’Brien was not entered in the Olympic event.
