Naoya Inoue did not plan on having a fight in January, and he did not plan on it being against an opponent that was determined just two weeks before the bout.

Everything else about ¡°Monster¡± Inoue¡¯s defense of his undisputed super bantamweight title, though, went exactly as expected.

Inoue (29-0) flattened South Korean challenger Kim Ye-joon 2:25 seconds into the fourth round to retain his WBA, WBC, IBF and WBO belts at Ariake Arena on Friday night.
