Boxing superstar Floyd Mayweather Jr said Monday he will come out of retirement to fight a Japanese kickboxer half his age, Tenshin Nasukawa, on New Year’s Eve in Saitama. The 41-year-old unbeaten American, who won world titles in five different weight divisions and was considered the best pound-for-pound boxer in the sport, out-boxed Irish mixed martial arts fighter Conor McGregor in his last fight in August 2017. That victory improved his boxing record to a perfect 50-0, but the format or rules for his meeting with the baby-faced Nasukawa were not specified by the Japanese mixed martial arts promoters RIZIN. Mayweather posted a teaser photo on his Instagram feed at the weekend, showing him wearing kickboxing gloves.
