Injin Chi v Eiichi Sugama

South Korea’s Injin Chi knocked out Eiichi Sugama in the 10th round to retain his WBC featherweight crown.

Chi, who won the title by stopping Michael Brodie in April in Manchester, made a successful first defence courtesy of a punishing combination in Saturday’s clash in Seoul.

Chi dominated the early stages but had a huge scare when he was caught by a big right from Sugama at the end of the sixth round.

For a while the result looked in the balance with Chi apparently weakened by having to lose nearly a kilogram before the weigh-in.

But the champion, known for his heart and relentless attacking style, gradually reasserted himself.

And he struck in the 10th, felling Sugama with a right-left combination.

The win improved Chi’s record to 29-2-1.
