Middleweights were limited to those boxers weighing less than 75 kilograms (165 lb).
[1] Like all Olympic boxing events, the competition was a straight single-elimination tournament.
Both semifinal losers were awarded bronze medals, so no boxers competed again after their first loss.
Punches scored only if the white area on the front of the glove made full contact with the front of the head or torso of the opponent.
The winner of the bout was the boxer who scored the most valid punches by the end of the bout.
