Jake Paul slammed Conor McGregor following the MMA star’s withdrawal from UFC 303.

Jake Paul pulled no punches as he ripped into Conor McGregor following his withdrawal from UFC 303.

McGregor’s comeback fight against Michael Chandler was postponed after the UFC star suffered an injury, forcing him to pull out of their welterweight clash.

A source close to the ‘Notorious’ has dropped a huge update on a new date for his UFC return.

Paul was asked about McGregor’s misstep in his comeback, and he held nothing back, claiming he’s ’embarrassing himself’ in a stinging rant.

On The MMA Hour, Ariel Helwani asked ‘The Problem Child’ whether he’d invite McGregor to his upcoming fight against Mike Perry to which he replied: “He needs to attend rehab.”

He added: “Look, we can get him a fourth or fifth row ticket. But he’s kind of lost his celebrity and star power. I don’t think people really care about him but I’m sure I could comp him a fourth or fifth row.”

Helwani countered by hailing McGregor’s star power, but Paul refuted the claim.

“I would disagree,” he said. “There’s new sheriffs in town. He hasn’t won a fight in what six or seven years? I don’t even know how long it’s been. He’s embarrassing himself. He’s ruining his legacy with all the drugs and the way he looks online. He’s lost his mind, he’s a maniac.

“At one point, Conor was great. Everyone loved Conor but I feel bad for the guy now. You could say all these things about him, but he hasn’t proven it, he hasn’t backed anything up and that’s the way I look at it is from the facts and the numbers.”

Paul is set to face former UFC fighter Perry on July 20 following the withdrawal of Mike Tyson.

But the 27-year-old’s fight against the former world heavyweight champion has been rescheduled for November 15.
