UFC President Dana White was never under the impression that retired former five division world champion Floyd Mayweather Jr. (49-0, 26KOs) would actually face UFC featherweight champion Conor McGregor.

Mayweather, 39-years-old, retired from boxing in September 2015 but was recently considering a bout with McGregor. The two fighters were going back in forth through social media for weeks, but then everything seemed to die down.
