In a sensational turn of events, Floyd Mayweather has denied agreeing to fight Japanese mixed martial artist Tenshin Nasukawa on New Year's eve.

Mayweather says he was "completely blindsided by the arrangements" and had "never heard" of the Japanese kickboxer until this week.

The undefeated boxer said that he was only asked to compete unofficially in a non-televised exhibition event for the "wealthy spectators" with an opponent (Nasukawa) selected by the Rizen Fighting Federation.

"First and foremost, I want it to be clear that I, Floyd Mayweather, never agreed to an official bout with Tenshin Nasukawa.

"In fact [with all due respect] I have never heard of him until this recent trip to Japan.

"I was asked to participate in a nine-minute exhibition of three rounds with an opponent selected by the Rizen Fighting Federation," he said in an elaborate Instagram post.

"Once I arrived to the press conference, my team and I were completely derailed," said Mayweather.

"We should have put a stop to it immediately.

"I can assure you that I too was completely blindsided by the arrangements that were being made without my consent nor approval. I was hesitant to create a huge disturbance by combating what was being said and for that I am truly sorry."
