Breaking!: Mayweather TKOs McGregor in 10th round of The Money Fight #MayweatherVsMCgregor

Floyd Mayweather has outclassed Conor McGregor to win their much-hyped super fight by TKO in Las Vegas to maintain his perfect record.

As hard as he tried, McGregor simply had no answer to the Mayweather's speed and technical ability as the undefeated American extended his record to 50-0.

Mayweather was happy to let McGregor start off as the aggressor in the first two rounds, watching as the Irishman mockingly put his gloves behind his back at one stage.

The American took his time to get going but gradually started throwing more punches once he'd had time to suss out McGregor's approach.

Mayweather really started to up the ante in the sixth round as hit McGregor with a succession of scoring punches.

The seventh round followed suit as 40-year-old Mayweather's boxing nous came to the fore.

Where the American had found himselves on the ropes in the earlier rounds, he began walking towards the Irishman with regularity as the bout wore on.

McGregor was visibly tiring in the ninth round and Mayweather went in for the kill with an exhibition of clean-punching too much for the UFC star to handle.

The referee eventually called the fight off in the tenth round.
