For several weeks - Skip Bayless, the former co-host of ESPN's First Take and current co-host of Undisputed on Fox Sports 1, was making wild predictions about Conor McGregor knocking out Floyd Mayweather Jr. last Saturday night.

McGregor, a two division champion in the UFC, was making his professional boxing debut. He started strong but faded as the fight played out and was ultimately stopped in the tenth round before a crowd of over 14,000 at T-Mobile Arena.

Bayless, true to form, is not taking McGregor's defeat on the chin.

Bayless believes McGregor was on the verge of securing the biggest upset in boxing history - but Mayweather was saved by the intervention of referee Robert Byrd.

According to Bayless, McGregor badly hurt Mayweather with a body shot at the start of the ninth round and was starting to work him over - but then Byrd jumped in, believing it was a low blow, and separated them to give Mayweather a moment to recover.

Bayless believes the shot was completely legal and Byrd's intervention saved Mayweather from a loss.

“The whole thing flipped and turned in round number nine. Floyd Mayweather was in trouble in this fight. But, the turning point to me, and I would like to see the video of this came in round nine," Bayless stated in a video posted to social media.

“Then in nine, he comes out aggressive and he stunned Floyd. He hit him with a hard left, rocked him and buckled him and Floyd’s in trouble in the corner and when Conor goes in for the kill..... it happened so fast [that] I need to see a replay, but he had him and Robert Byrd pulls him away. In that moment, I thought that’s it. Again, I’m just going off my instinct, my gut and Conor had him on the ropes. He was then backed off to the middle of the ring and he had spent himself on that salvo. Eight took a lot out of McGregor.

“He took a shot to end it early in round nine and he got pulled off. I swear Robert Byrd saved the fight. He saved it. Byrd, longtime referee in Las Vegas, highly respected - but he gave Floyd a big break he didn’t deserve.”
