Rumors that Conor McGregor got knocked out in a sparring session ahead of his boxing showdown with Floyd Mayweather Jr. have been spreading online.
Mayweather, however, remains skeptical unless he has evidence.
“My take is if I ain't seen no footage, I don't believe it,” the American boxer, who has yet to see a loss in 49 fights, told Fight Hype.
Former welterweight champion Jessie Vargas was earlier quoted as saying that he heard about McGregor being knocked out in sparring while preparing for his high-profile bout with Mayweather.
“They said he got knocked out in sparring already, man,” Vargas told Bleacher Report.
“The boxing world is small, it's a small circle.”
But Mayweather said he has been in touch with Vargas to check out his sources.
“We're working on Vargas to sign with Mayweather Promotions, so we've been communicating,” he said.
“But everything is just rumor until I see it. I have to see (the knockout) with my own eyes.”
The unbeaten boxer is wary about being manipulated into underestimating McGregor, a mixed martial arts superstar with no prior experience to professional boxing.
In a previous statement, he said Manny Pacquiao’s defeat to unheralded Jeff Horn is proof that anyone can pull off an upset.
"That's why I can't overlook Conor McGregor. Anything can happen," he said.
