Keith Thurman Calls Out Conor McGregor, 'Box Me, Baby'

If Conor McGregor wants another crack at a top flight boxer, Keith Thurman says he's ALL THE WAY DOWN -- telling the Irishman straight up, "Box me, baby!!"

Of course, Thurman -- the WBA super welterweight champ -- is gearing up to face Manny Pacquaio on July 20 ... but says he's heard about Conor's desire to get back in the ring and wants that fight!

"You know you make more money in the boxing ring anyway. Box me, Conor!"

Thurman's not kidding ... he watched the McGregor vs. Mayweather fight back in 2017 and sees major holes in Conor's fight game.

"[In boxing], the advantage is do you have skills with the left? Do you have skills with the right? Do you have footwork? And, one thing [Conor] doesn't have is conditioning! He does not have conditioning. He is not ready for these championship fights."

"Floyd walked him down and beat him like he was playing 'Fight Night!'"

Thurman continued ... "He wanna talk that trash?! He wants to think actually got hands? Come on, man."

McGregor recently told Tony Robbins he wants a rematch with Floyd Mayweather because he's learned so much from the first fight and KNOWS he could get a win.
