Watch Jake Paul brutally KNOCK OUT Andre August with uppercut in first round and already has next fight lined up

JAKE PAUL brutally knocked out Andre August in the first round with a brutal right uppercut.

The YouTuber-turned prizefighter marked a new step in his career by facing a professional boxer with more experience.

And a perfectly-timed uppercut left August unable to beat the count and Paul handed the most legitimate win of his career.

He said: "I said first round knockout all week, I manifested this, this is the power of manifestation and I said I need to bring back the old Problem Child.

"I've been too nice with these people, letting them go into the later rounds. I set up my shot and he went night, night.

"I told him he was going to need a Celcius to wake up."

From the opening bell, Paul, 26, took the centre of the ring and got behind his jab.

He was doubling up his left hand and looking for the right behind it but August - who had 12 prior bouts - covered up well.

The little-known American, 36, also landed a couple of solid overhand rights himself but Paul took them well.

And then as the round was closing out, Paul set August up with a range-finding jab before firing over the finishing uppercut.

Immediately the social media sensation walked over to the camera with a smirk and put his finger to his mouth.

He said: "Just silencing the critics, everyone who had something to say about me, 'Oh, he can't do this, he can't sell, he's not big, what is he doing fighting this guy? Fighting that guy,' shut the f*** up."

Paul teased that he has an announcement for his next fight lined up next week as he looks to face more seasoned boxers.

He was beaten by Tommy Fury, 24, by split-decision in Saudi Arabia but bounced back in August to beat ex-UFC star Nate Diaz, 38.

But Paul said on his next fight: "More boxing prospects, more experience, more time in the ring under the bright lights staying active.

"And if the money fights want to come, I've got smoke for them too but right now I'm focussed on being one of the best in the world and creating one of the greatest sports stories in the history of sports.

"Being able to become a world champion from Disney channel, three years ago not even knowing how to throw a jab or what an uppercut was."
