Mayweather bests McGregor in 10th round TKO

LAS VEGAS -- Floyd Mayweather Jr. stopped UFC champion Conor McGregor on his feet in the 10th round Saturday night, ending the boxing spectacle of the summer with a harsh dose of reality.

The most unusual megafight in years went longer and was more competitive than many expected when an unbeaten, five-division world champion boxer took on a mixed martial artist making his pro boxing debut.

While McGregor (0-1) had the T-Mobile Arena crowd behind his improbable quest, Mayweather (50-0) survived a rough beginning and gradually took control. He brutalized McGregor in the 10th, landing numerous shots and chasing McGregor around the ring until referee Robert Byrd saved the Irishman and stopped the fight.
