Conor McGregor in racism controversy after Instagram post Floyd Mayweather and Tenshin Nasukawa

Conor McGregor has had controversial racism again with a social media post comparison Floyd Mayweather and Japanese kickboxing sensation Tenshin Nasukawa to Chris Tucker and Jackie Chan.

Nasukawa, a 20-year-old undefeated kickboxing and karate specialist, in a fight with a Japanese student in the Japanese city of Saitama on New Year's Eve.

McGregor, who had been talking about an option for Mayweather's comeback fight, mocked the American's choice of opponent in a foul-mouthed Instagram post-but in doing so he compared the 41-year-old boxing great to comedian Tucker and Nasukawa to legendary Hong Kong martial artist and actor Chan, in a reference to the pair's collaboration in the 'Rush Hour' franchise film.

"What in the f *** is going on here?" McGregor wrote a picture of Mayweather and Nasukawa posing together at the press conference to announce the fight. "Who's this little p *** next to you? That's mad s ***. Like something out of rush hour 5 or something.

"Chris tucker and Jackie f *** ing Chan back in this bitch. F *** ing brilliant. Mad little b *** ard you are Floyd. Fair f *** s to you mate. No lie. F *** it. "

The post prompted a backlash online, with many pointing out McGregor's problematic equating of a Japanese kickboxer to a Hong Kong star movie and others coming to his defense.

This is not the first time McGregor has made racially or culturally insensitive comments. Back in 2015 he called German fighter Dennis Siver a "Nazi", and then goaded Brazilian opponent Jose Aldo by saying that in previous times "I would invade his favela on horseback and would kill anyone who was not fit to work".

In the lead-up to his blockbuster promotion against Mayweather in 2017, McGregor was accused of racism after instructing the American during a press conference to "dance for me, boy". When the implications of his words were put to him, he said he could not possibly be racist because he is "black from the bellybutton down".

UFC Lightweight Champion Khabib Nurmagomedov in October, McGregor's last fight was a comprehensive defeat. Once again, it is confirmed that the McGregor's camp, sparking violence inside and outside the arena, after the Irishman insulted his country and religion during the promotion for the contest.

As a result of the incident, both men are currently banned indefinitely by the Nevada State Athletic Commission.
