Olympic gold medal-winning boxer Teofilo Stevenson died from a heart attack in Havana, Cuban state media reported Monday, quoted by CNN. He was 60 years old. Stevenson won three Olympic gold medals fighting for Cuba and is still tied for the record in the sport. Boxing was briefly banned after Cuba’s 1959 revolution. But with the help of Soviet trainers, Cuba soon became a powerhouse in the sport, with Stevenson as one of the island’s most famous fighters.
