Jake Paul calls out UFC champion after his gruelling six-round knockout win against Mike Perry - before FaceTiming him in the ring!

Jake Paul wasted no time in setting up future bouts after his devastating sixth-round knockout win against former UFC star Mike Perry on Saturday night. 

The bombastic Youtuber-turned-boxer unleashed a barrage of punches on the 32-year-old Bare Knuckle Fighting champion that sent him to the canvas. 

It was the third time in the clash Paul had done so and, after Perry somehow rose to his feet, the referee rightly waved off the contest. 

Perry had been a last-minute replacement for Mike Tyson after the boxing legend pulled out of his proposed showdown and Paul was quick to urge the veteran to 'sign the contract' ahead of their proposed November bout. 

The 27-year-old also took the chance to call out UFC Light Heavyweight champion Alex Pereira. 

'Alex Pereira, you said you wanna box... I'm the king of this, come over and we can make it happen,' he said. 'I want you Alex Pereira.' 

Paul was even spotted FaceTiming the UFC champion in the ring, with one user on X claiming that Pereira swiftly contacted his would-be opponent after hearing of his taunt. 

The 37-year-old recently stepped up on late notice to save UFC 303.

Conor McGregor withdrew from the card and was replaced by Pereira, who easily defended his belt by brutally knocking out former 205lb champion Jiri Prochazka. 

Paul meanwhile, has now racked up four straight victories since slumping to the first defeat of his professional career against Tommy Fury last year.

Perry is the fifth ex-UFC fighter he has defeated; following his wins over Nate Diaz, Anderson Silva, Tyron Woodley and Ben Askren.

Next up for the online superstar is former undisputed heavyweight champion Tyson, who will be 58-years-old by the time he steps into the ring.
