1993-05-28 Jung-Il Byun w pts 12 Josefino Suarez, Inter-Continental Hotel, Seoul, South Korea - WBC. Referee: Richard Steele. Scorecards: 120-104, 120-106, 119-109. Starting fast, the southpaw champion dropped Suarez (116¾) with a cracking left in the opening round, but from then on, although winning handsomely, Byun (117¾) appeared to lack the power to take out the teak-tough, stationery Mexican who absorbed punishment throughout.
With Byun unable to defend his WBC title due to an injured hand, Joichiro Tatsuyoshi outpointed Victor Rabanales over 12 rounds at the Prefectural Gym, Osaka, Japan on 22 July in a battle to decide the ‘interim’ title, but on Byun's return to the ring it was another Japanese fighter, Yasuei Yakushiji, who challenged him due to Tatsuyoshi being banned by the Japanese Boxing Commission after they became dissatisfied with his eye condition. However, they later relented when making a ‘special ruling’ that he could participate in Japan as long as the contest carried a world title label.
