Mayweather gets knocked out by sparring partner - report

Undefeated American champion Floyd Mayweather Jr. reportedly got knocked out by his sparring partner, Zab Judah, during a practice last Sunday.

"Zab hit Mayweather with a good shot, a left hook to the body, and he went down," a source, who was at the Mayweather Boxing Club, told

"To my knowledge Money has never gone down ever. Not in sparring, or in the ring," the insider, who spoke on the condition of anonymity, reportedly said.

"It's not unusual for a boxer to get hit hard in training and go down. And Floyd responded well. When he got up, he finished the session," the website's source added. "And he beat Zab to a bloody pulp, however he was down for more than a 10 count so technically he was knocked out."

During their fight in 2011, Judah scored a knockdown in the second round when Mayweather's glove touched the canvas. However, referee Richard Steele ruled it a slip.

Here's a video replay of that bout:

Mayweather (47-0, 26 KOs) will face Filipino boxing icon Manny Pacquiao for the mega-fight of the century at the MGM Grand Garden Arena in Las Vegas, Nevada on May 2, 2015.
