When it comes to combat athletes, McGregor is comfortably ahead of the competition with current UFC lightweight champion Khabib Nurmagomedov – who beat the Irishman last year – second on 111.1m.
Then come Anthony Joshua (41.6m), Floyd Mayweather (31.4m) and Canelo Alvarez (26m).
McGregor has not fought since his fourth-round submission defeat by Nurmagomedov last October.
“I think McGregor is gonna come back at the beginning of next year,” UFC president Dana White told the Rich Eisen show in the US.
Conor McGregor UFC return date revealed as Dana White issues update
McGregor’s opponent remains unclear with many on the roster calling out the former lightweight champion.
Nurmagomedov takes on Dustin Poirier in a unification bout in Abu Dhabi on September 7 and White is not ruling out the Russian facing off against McGreor in a rematch.
“It would be a massive fight and it’s absolutely possible, yes.
“It’s a very interesting division because you have Khabib, you have Tony Ferguson, Conor McGregor , Donald Cerrone, Justin Gaethje – there’s just so many unbelievable fights in that weight class.”
McGregor could also fight Nate Diaz in a trilogy clash following their epic fights in 2016.
