Floyd Mayweather will take part in an exhibition fight against mixed martial arts fighter Mikuru Asakura in Japan later this year, organizers said on Tuesday. American Mayweather, who was inducted into the International Boxing Hall of Fame on Sunday, retired in 2015 but returned to defeat Conor McGregor in 2017 and improve his professional record to 50-0. Promoters said the bout is scheduled for September. The exact date, venue and rules for the fight will be announced later this month. This will be Mayweather’s second exhibition bout in Japan, following his first round TKO win over kickboxer Tenshin Nasukawa in 2018.
