Kiyoshi Tanabe

As an amateur Tanabe won a bronze medal at the 1960 Olympics, becoming the first Japanese boxer to win an Olympic medal. His amateur record was 115-5 (30RSC). He made his professional debut in 1963, and won the Japanese flyweight title in 1965, which he defended twice before vacating. In February 1967, he fought WBA & WBC flyweight champion Horacio Accavallo in a non-title match, and won by 6th-round TKO.[2]

Tanabe was scheduled to get his first world title shot in July 1967, and expectations heightened around the talented fighter. However, it was discovered that he had suffered a detached retina in his right eye, which forced him into retirement. He had surgery on his right eye, but lost his vision two years later.
