The first matchup between a professional boxer and a mixed martial arts fighter ended with Floyd Mayweather being victorious. In the 10th round, Floyd unleashed a flurry of punches against McGregor to the point where the referee had to stop the fight, giving Mayweather a technical knockout. The 40-year-old Mayweather is now 50-0 in his professional boxing career.

In the post-fight interview, Mayweather announced that this will be his last fight. McGregor stated that he felt the referee stopped the fight too early, and he should have been allowed to keep fighting.

Mayweather walked away roughly $100 million from the fight, while McGregor earned an estimated $30 million. Mayweather's lifetime earnings are roughly $1 billion.
