Yuriorkis Gamboa
Several medalists at the 2004 Olympics, including Amir Khan, Andre Ward, Gennady Golovkin, Yuriorkis Gamboa, and Guillermo Rigondeaux, later went on to become world champions in professional boxing. However, Russian boxers don’t typically turn pro as their government provides them with extensive funding which allows them to keep their “amateur” status and compete at multiple Olympics. The tournament was also Mario Kindelán's final Olympic event before retirement, with a second lightweight gold metal after beating Amir Khan.
