On Aug. 26 at the T-Mobile Arena in Las Vegas, Floyd Mayweather Jr. will face off against UFC lightweight champion Conor McGregor in a 12-round boxing match. Combat sports fans anticipate Mayweather Jr. beating McGregor handily.

During an interview with Helen Yee of NBC Sports Radio, head trainer and Mayweather Jr.’s father, Floyd Mayweather Sr. said his son will have some tricks up his sleeve for the MMA star.

“Floyd’s gonna definitely put something on Conor McGregor. I’ve got a few presents for Conor McGregor,” Mayweather Sr. said. “I’ve got a few things that I want to hand him. There are a few things that I want to do, and things that Floyd can do. We’re going to be able to touch him up real good.”

Mayweather Jr. is 49-0 and regarded as the greatest boxer of this generation and one of the greatest defensive pugilists of all-time while McGregor’s never had an amateur or professional bout. Many feel McGregor does have advantages in terms of power, being the bigger fighter and is 12 years younger than Mayweather Jr. But Mayweather Sr. feels none of those factors will come into play.

“Let me tell you something, even if it goes the distance, [Floyd] is going to whoop his ass. That’s what’s going to happen. Any way he wants to do it, [McGregor] is gonna get whooped. Ain’t nobody gonna say I’m wrong because they know he’s going to get whooped anyway.”

Based off those statements, Mayweather Sr. proclaims after all is said and done, his son will make sure McGregor will never be the same fighter.

“Conor McGregor won’t be able to spell anything (after the fight).”
