Floyd Mayweather, 41 will make a surprise comeback on New Year’s Eve against 20-year-old Japanese kickboxing sensation Tenshin Nasukawa at the Saitama Super Arena.
Mayweather, undefeated in 50 fights and a world champion in five boxing weight divisions, said the rules of the bout have yet to be clarified.
Nobuyuki Sakakibara, a Japanese businessman, renowned mixed martial arts promoter and president of Rizin Fighting Federation, said there are several aspects of the bout still to be finalised.
Mayweather is 50-0 as a boxer with 21 knockouts, and most recently defeated McGregor when McGregor transitioned from the UFC Octagon to the boxing ring.
Nasukawa has a 27-0 record with 21 knockouts in kickboxing and 4-0 with two knockouts in MMA. He recently defeated former UFC flyweight fighter Kyoji Horiguchi in a kickboxing fight. Southpaw Nasukawa holds the Rizin featherweight title, which is 20 pounds lighter than Mayweather’s fighting weight.
Mayweather expect to bring in more than $100 million for the contest, which is almost certain to be pay per view.
He earned more than $240m for fighting UFC star Conor McGregor 17 months ago in Las Vegas, and has been involved in four of the top five biggest grossing fights in combat sports history.
