Dana White Wants Floyd Mayweather to Retire, Undecided on Logan Paul in UFC

Dana White tells TMZ Sports ... he hopes Floyd Mayweather finally hangs up the gloves after his exhibition with Logan Paul.

... but as for Logan Paul fighting in the UFC one day, Dana ain't exactly saying no!

INTERESTING!!!

First, Floyd ...

"I would love to see Floyd retire," White tells us ... "He's had an incredible career and to do these type of fights, it's silly."

Now, to Logan ... who has repeatedly said he would kill for a shot to fight in the UFC since he has a legitimate wrestling background and feels he could actually compete in the Octagon.

So, Dana ... would you ever sign Logan Paul to a UFC deal?

"I don't know man ... I don't know."

"Here's the thing, not to say that I haven't taken a guy in that's been 0-0 into the UFC and done those types of fights before ... I don't know."

White is obviously referencing CM Punk, the former WWE superstar who got 2 fights in the UFC despite no prior professional MMA experience. Punk lost both of his fights in a lopsided fashion.

But, White respects Logan's work ethic and athletic ability -- as well as his marketing power ... and says there will always be a market for famous people to get in the ring.

"Imagine if Kim Kardashian wanted to fight Amanda Nunes ... how big do you think that fight would be?!"

"What do you think Kim Kardashian would make if she fought Amanda Nunes ... probably more than anybody's ever made, ever!"
