Mayweather moved to 50-0 as a professional. McGregor, a mixed martial artist, took a hard-fought loss in the first boxing match of his career.
Both fighters made bold claims about their ability to crush the other. In the days leading up to the fight, Mayweather guaranteed he’d knock out McGregor.
Although McGregor is one of the biggest stars in mixed martial arts, he had not boxed since he was a teenager, and had no professional boxing matches under his belt.
The fight was fashioned on the strength of two bombastic personalities with huge fan bases, making for a ripe promotional draw.
