Mayweather beats kickboxer Nasukawa

Floyd Mayweather needed just 140 seconds to beat Japanese kickboxer Tenshin Nasukawa in an exhibition boxing bout worth a reported $9m.

Former five-weight world champion Mayweather, 41, was smiling during the short-lived contest in Tokyo as he floored the 20-year-old three times.

The fight, scheduled for three-minute rounds, ended with Nasukawa in tears as his team threw in the towel.

Despite his latest comeback, Mayweather said afterwards he was “still retired”.

And after beating Nasukawa, Mayweather insisted: “I’m still undefeated; Tenshin is still undefeated. Tenshin is a true champion and a hell of a fighter.”

Addressing the Japanese fighter, he added: “Hold your head up high.

“I want the fans around the world to support Tenshin, he’s a great guy and a great champion.”
