Floyd Mayweather defeated Japanese kickboxer Tenshin Nasukawa in an exhibition boxing bout worth a reported USD$9m.
The fight lasted within 140 seconds.
41-year-old former five weight world champion world champion Mayweather was smiling during the short‑lived contest in Tokyo as he floored the 20‑year‑old three times.
The fight, scheduled for three rounds, ended with Nasukawa in tears as his team threw in the towel.
Despite his latest comeback, Mayweather said that he was still retired.
The rules were very strictly defined with kickboxer Nasukawa reportedly facing a $5m fine if he aimed a kick at his older opponent.
Mayweather also came out of retirement last year to beat McGregor in the Irishman's first ever boxing match.
