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. Bouts consisted of three rounds of three minutes each, with one-minute breaks between rounds. Punches scored only if the front of the glove made full contact with the front of the head or torso of the opponent. Five judges scored each bout; three of the judges had to signal a scoring punch within one second for the punch to score. The winner of the bout was the boxer who scored the most valid punches by the end of the bout.
On 8 May 2011 Manju Wanniarachchi was provisionally disqualified by the Commonwealth Games Federation after testing positive for Norandrosterone during the Games. He had 21 days to appeal the decision but on 26 May announced that he did not wish to file an appeal and retired from the sport. On 6 June 2011 the Commonwealth Games Federation announced Sean McGoldrick of Wales as the new gold medallist. Tirafalo Seoko of Botswana was upgraded from bronze to silver on the basis that he had lost to Wanniarachchi in the semi-finals.
