Although Mayweather is the undisputed champ of big-time paydays, Conor McGregor is no slouch when it comes to making money.
McGregor brought in a whopping $99 million for his efforts in the ring.
Keep in mind he owe's that massive sum to Mayweather, as $85 million came from McGregor's lone fight against Mayweather in 2017.
The Irish fighter collected another cool $14 million from endorsements.
McGregor (21-3) is expected to step back into the UFC Octagon this fall when he takes on undefeated Khabib Nurmagomedov (26-0.)
