“My thing basically is like this: If I ain’t seen no footage, I don’t believe it,” Mayweather said to Fight Hype. “Me and Jessie Vargas are in communication. We’re talking about working together with Mayweather Promotions. I would love to work with Jessie Vargas. We’ve been communicating. But I can’t—everything is rumors until I see it. I’m the type of person, I have to visually see it with my own eyes.”

Listen to Vargas talk about McGregor’s alleged knock out:

While McGregor hasn’t responded directly to the knockout allegations, the UFC star did post a photo on Instagram late Monday night along with the caption, “Sparring today.”
