- Inoue defends WBA, WBC, IBF and WBO titles at 122lbs
- Japanese star boosts claim as pound-for-pound No 1
- As it happened: Bryan Graham’s round-by-round report
Japanese boxing superstar Naoya Inoue remained the undisputed world super-bantamweight champion when Irish challenger TJ Doheny dropped to his knee and quit in the seventh round because of an apparent back injury on Tuesday.
Doheny complained of a “twinge” after walking back to his corner gingerly. Before then, he was getting pummeled by Inoue, who celebrated his technical knockout – for a 28th successive win – in muted fashion in Tokyo.
