Friday afternoon in London, boxing icon Floyd Mayweather and UFC lightweight champion Conor McGregor appeared in a boxing ring together for the first, and only, time ahead of their showdown on August 26th.

The press conference was the most intense one throughout the course of the world tour, that even saw Conor McGregor physically touch Mayweather for the first and only time throughout the world tour, as he rubbed Mayweather’s head during his speech to those in attendance.
