Aydin İbrahimov was the second Azerbaijani freestyle bantamweight, after Rəşid Məmmədbəyov, to win an Olympic medal. İbrahimov rose to prominence at the 1960 Soviet Championships, where he won a bronze medal, and first competed internationally at the 1963 World Championships, where he won gold. İbrahimov was expected to repeat that victory at the 1964 Olympics, but losses to Yojiro Uetake and Hüseyin Akbaŝ in the final round left him with a bronze medal. İbrahimov last competed internationally at the 1966 European Championships, where he won gold. Domestically, in addition to his 1960 bronze, İbrahimov won the Soviet freestyle bantamweight title in 1964, silver in 1963 and bronze in 1967. After finishing his sporting career, İbrahimov worked as a wrestling coach in his native Azerbaijan.
