Floyd Mayweather beats McGregor in their million dollar fight (photos)

Boxing Champion, Floyd Mayweather in his return from a two-year retirement improved to 50-0 with a 10th-round TKO over an incredibly game Conor McGregor in their pay-per-view superfight at T-Mobile Arena.

But the storyline was just as much about McGregor, the UFC lightweight champion, in defeat than it was about the 40-year-old Mayweather in victory.

McGregor, 29, who was making his debut as a boxer, never fought reckless or overly aggressive, in contrast to his prediction of a first-round knockout. What he did was present Mayweather with a poised and credible challenge, teasing a bright future in the boxing game should he consider it.

"He's a lot better than I thought he was," Mayweather said. "He used different angles. He was a tough competitor, but I was the better man tonight.

"We talked about how he's a tough competitor, and I think we gave the fans what they wanted to see. I chose a hell of a dance partner to dance with. Conor McGregor, you are a hell of a champion."

Mayweather officially announced his retirement after the fight.
