Conor McGregor likely silenced many of his critics in the boxing world tonight, but the UFC champ ultimately came up short against Floyd Mayweather.

McGregor proved to be a considerable challenge for Mayweather in the opening rounds, as he outstruck the undefeated boxer. But, as the fight wore on, Mayweather began reading his opponent, and picked up the pace while McGregor started to tire. In round ten, after Mayweather cracked McGregor with several, thumping rights, the bout was called.

It was a very impressive outing for McGregor, who was making his pro-boxing debut.
