Japanese kickboxing sensation Tenshin Nasukawa has accepted Conor McGregor's challenge for another exhibition fight in Tokyo, but only under kickboxing rules.
Nasukawa was in tears after Floyd Mayweather knocked him out in the first round of an exhibition boxing bout on New Year's Eve.
Mayweather, 41-years-old and a former five division world champion, dropped the 20-year-old Nasukawa three times before the corner threw in the towel.
McGregor, a two division UFC champion, has now called out the unbeaten Japanese kickboxer for what he clearly hopes will be a lucrative payday of his own.
The UFC superstar could be looking to upstage Mayweather's recent event.
Mayweather and McGregor collided in a very lucrative cross-sport boxing match in August 2017 at the T-Mobile Arena in Las Vegas.
McGregor did well in the early rounds, but he was slowly broken down and stopped in the tenth round. Mayweather retired following the bout - while McGregor has been pushing for a rematch.
Now the Irish fighter wants to face Mayweather's last opponent.
"I wish to go to Tokyo to face Tenshin Nasukawa in a Mixed Martial Arts exhibition bout. Before this summer. Please arrange this, this instant. Yours sincerely. "The champ champ," McGregor stated on social media.
Nasukawa offered a positive response to McGregor on Monday, but only on his terms.
He was actually surprised that McGregor even challenged him or knew his name - but outlined terms that are likely never going to get an exhibition fight done. Nasukawa is not taking the bait this time, and wants a much lower weight limit.
He usually fights at 122 to 126-pounds and fought Mayweather at the welterweight limit of 147. Mayweather was huge compared to Nasukawa - and McGregor is even physically bigger than Mayweather.
"Dear Mr. McGregor. Thank you very much for remembering my name," said the 20-year-old.
"I'm honoured that you would even consider fighting me. 58kg [128-pounds], kickboxing rules would probably get us in the ring sometime in the near future."
