McGregor, 27, has been in discussions with the undefeated pound for pound king for the last few weeks about a multi-million dollar welterweight bout and has begun sharpening his tools accordingly.
The Irishman began his career in the sport as a youngster before switching his hand to MMA at 16 with considerable success – but is now set for a spectacular return at the highest level possible.
In preparation, McGregor shared a few rounds with former IBO title holder Chris Van Heerden as the ‘Notorious’ one gets reacquainted with only using his fists once again.
