Jake Paul brutally mocked by Dana White for boxing '40-year-old MMA fighter' Nate Diaz

UFC president Dana White has ruthlessly mocked Jake Paul for boxing Nate Diaz following his crushing defeat to Tommy Fury.

'The Problem Child' suffered the first defeat of his professional career to Fury, who scored a split-decision victory in Saudi Arabia earlier this year.

He will look to get back to winning ways when he welcomes former UFC superstar Diaz to the squared circle.

The Stockton slugger fought out his UFC contract after submitting Tony Ferguson in the main-event of UFC 279 last September.

He will try his hand at boxing when he takes on Paul in an eight-round clash on August 5 in Dallas, Texas.

But despite the high-profile boxing match, UFC chief White isn't into it as he slammed Paul for facing an ageing fighter.

Speaking on The Jim Rome show, he said: "I don’t know, man.

"I’ve been trying not to [criticize it]. I like Nate. Nate and I have a good relationship. Listen, Jake Paul went out and fought a real boxer who was his age, his weight, and he lost."

White added: "So as soon as he loses, he goes back to a 40-year-old MMA fighter who’s smaller than him [and] not his weight.

"Listen, it’s just one of those fights. I know that some people are into this. It’s just not what I’m into. It’s not my thing."

Paul, 26, is 12 years younger than Diaz, who is renowned for his hands in MMA.

But White doesn't like his chances considering his age and the fact that they are fighting at a catchweight of 185lbs.

During his legendary UFC career, the 38-year-old fought at lightweight and welterweight, but mainly campaigned at 170lbs, where he boasts a big victory over Conor McGregor.
