Hiroki Ioka (9-0, 5) vs Kyung Yung Lee (11-0, 4)
In 1987 we saw the recognition of the Minimumweight division. the first champion of which was IBF title holder Kyung Yung Lee [이경연]. Lee vacated the title soon after winning it to face WBC champion Hiroki Ioka [井岡 弘樹], who had become the youngest Japanese world champion when he had won his title in October 1987. Essentially these were the two best 105lb fighters and both were wanting to prove it.
