Mayweather Sr.: Floyd has 'hand problem' that will limit KO power

Floyd Mayweather Jr. may have a few bumps and bruises heading into his blockbuster bout with Conor McGregor.

Floyd Mayweather Sr. told FOX Sports 11 that he doesn't expect his son to knock out McGregor when the two meet in their Aug. 26 boxing match due to an issue with Mayweather Jr.'s hand.

"I ain't gonna say a knockout, because my son got a hand problem," Mayweather Sr. said Tuesday. "That's a true story, he got a hand problem."

Mayweather Sr. declined to elaborate on the severity of the "problem" or specify whether it affected both hands, but he remained confident that his son will dispatch the UFC lightweight champion with ease in Las Vegas.

"He gonna make Conor McGregor look like a fool," said Mayweather Sr. "Believe me."

Even with a 49-0 record, Mayweather Jr. has never been known for his concussive knockout power. He hasn't finished an opponent inside the distance since beating Victor Ortiz in the fourth round of a Sept. 17, 2011 contest, and even that result was shrouded in controversy when Mayweather appeared to land shots on an unprepared Ortiz following a break in action.
