UFC superstar Conor McGregor appears to have turned his back on a potential rematch with Floyd Mayweather - by posting on social media that the retired five division world champion has pulled out of claimed rematch negotiations for a potential mixed martial arts encounter.

McGregor, 29 years old, made his boxing debut last August and suffered a tenth round TKO at the hands of Mayweather at the T-Mobile Arena in Las Vegas.

MMA reporter Mike Bohn had tweeted: “Just saw Floyd Mayweather as I was walking backstage [at the NBA All Star Game] and asked him if he’s serious about a rematch with [McGregor] in MMA: “I already fought Conor, and we’re at a basketball game, not an MMA match.”

And McGregor’s Instagram response read: “I am happy for Floyd and his recent announcement that he is out of these current fight negotiations.

“It is the reason I never seeked the rematch in the first place. I was happy for him in retirement.

“My game is a very unforgiving one. It is not like other games. I understand completely him staying retired. I will now carry on in my negotiations and see where it goes.

“Have a great retirement Junior. Now come here and give your old man a hug for old times sake. I’m proud of you son. Yours truly, Senior.”

In recent weeks, Mayweather released a series of videos on social media showing him stepping into an octagon and sparking rumours of a UFC clash with the Dubliner

McGregor gave his take, saying: “If it is (hype), it will follow him for the rest of his days that he did not do it. I said that I’d do it and I stepped up and I done it. It’s his turn now.”

UFC fans have been calling for McGregor to defend the lightweight belt he won against Eddie Alvarez in November 2016.
