The Greco-Roman lightweight competition at the 1912 Summer Olympics was part of the wrestling programme. The competition used a form of double-elimination tournament. Rather than using the brackets that are now standard for double-elimination contests (and which assure that each match is between two competitors with the same number of losses), each wrestler drew a number. Each man would face off against the wrestler with the next number, provided he had not already faced that wrestler and that the wrestler was not from the same nation as him (unless this was necessary to avoid byes).
