Watch: Mayweather dubs McGregor the 'Caucasian Floyd Mayweather'

Floyd Mayweather Jr. praised former rival Conor McGregor while appearing on a recent episode of comedian Kevin Hart's Youtube series "Cold As Balls."

"He's the Caucasian Floyd Mayweather. He's a knockoff. He's a hell of a knockoff version," Mayweather said.

When asked if there's respect between the two following their 2017 boxing match, Mayweather replied, "Yeah, I take my hat off to him. I mean, he's a dog."

Mayweather was also asked about fighting in the Octagon - something he teased last year - and while he acknowledged "anything is possible," it doesn't sound like the 41-year-old is in a rush to make it happen.
