Retired boxing icon Floyd Mayweather Jr. looks like he’s going to give Conor McGregor the beatdown of a lifetime. The polished fighter has treated the world to a sneak peek at his training.

Floyd went to Instagram Thursday (June 29) with a savage clip of himself putting in work at the gym.

McGregor has also kept busy flooding his IG page with troll-like pics.

According to reports, Mayweather is expected to land around $300 million for the August 26 fight.
