The Olympic champion and three-time world boxing champion in the professional ring had legal issues. He fatally wounded a person, though external circumstances — lack of street lighting and absence of banned substances in his body — allowed him to spend a short time in prison. Gamboa also had to take a long time to get his passport back.
Eventually, the Cuban returned to Miami, resumed training under the guidance of Pedro Diaz, and signed a contract with the BKB (Bare Knuckle Boxing) federation. It is expected that the organizers will soon announce the date of Gamboa's debut in the new format for him.
