Current UFC lightweight champion Conor McGregor will take his talents to the squared circle tomorrow night in Las Vegas when he throws down with undefeated boxing legend Floyd Mayweather.

The Mayweather vs McGregor “super fight” could potentially end up being the biggest fight in combat sports history.

Saturday night’s pay-per-view event is expected to do huge numbers and as a result both Floyd Mayweather and Conor McGregor will earn massive guaranteed paydays.

ESPN’s Brett Okamoto recently revealed both Conor McGregor and Floyd Mayweather’s guaranteed fight purses on Twitter:

Disclosed, guaranteed purse amounts for tomorrow: Floyd Mayweather $100 million, Conor McGregor $30 million. Both will ultimately make more.

Of course both Floyd Mayweather and Conor McGregor could potentially earn much more depending on the success of the pay-per-view event.

Conor McGregor was last seen in combat at November’s UFC 205 event in New York, where he earned a second-round knockout victory over Eddie Alvarez to become the UFC’s undisputed lightweight champion of the world.

As for Floyd Mayweather, “Money” has not competed inside the squared circle in over two years. In his most recent appearance Mayweather earned a unanimous decision victory over Andre Berto.
