Conor McGregor’s crossover fight against Floyd Mayweather in August sent the world into a spin as the undefeated boxing star took home his 50th win in the ring.

McGregor showed promise early on in the bout, taking the first few rounds by bullying Mayweather with his superior reach.

But Mayweather was able to get the 29-year-old’s measure and shut him out in the 10th round via TKO.

Controversy erupted over the result immediately after the fight with McGregor himself admitting he was “shocked” at the scoring. The MMA star later announced he was faring well under Mayweather’s beating despite constantly losing his balance, prompting a former boxing doctor to declare he was in danger of brain trauma.

A fresh crop of videos of Mayweather working out have been posted to his Instagram account, which has iconic sportscaster Jim Lampley suspicious.

“Why else is he putting out videos of him working out?” Lampley told TMZ. “He allowed Conor McGregor to ‘win’ three rounds. Why did the whole thing last 10 rounds, etc.? It’s all a setup.”

Lampley said Mayweather could easily make another $150 million from a rematch with the UFC lightweight champion, claiming “suckers” would be drawn to the spectacle.

“Why should he retire?” Lampley said. “He created a marvelous scam with this whole thing. He allowed Conor to quote ‘win’ three rounds, so the whole global MMA wish community could have something to latch onto.

“I think there’s a decent chance, there’s enough suckers out there, Floyd could maybe make another $150 million. Why not?”

When asked if he thought Mayweather threw some rounds, Lampley immediately replied, “Obviously.” Then he was asked if he thought Mayweather would be stupid enough to risk his legendary undefeated record for another shot at McGregor, Lampley replied in incredulity.

“Risk?” Lampley said. “Risk? Did you just associate the word risk with Floyd Mayweather? This is not about risk, young man. Risk has nothing to do with it. There’s no risk involved for him.

“So we’re betting on the question, does Floyd want to make another $150 million? Why would that even be a bet?”
