Youtube star turned boxer Jake Paul (4-0, 3 KOs) is very confident in his ability to score a knockout of upcoming opponent Tommy Fury (7-0, 4 KOs).

The two rivals will collide in the main event of a Showtime pay-per-view card on December 18th from the Amalie Arena in Tampa Bay, Florida.

The 24-year-old Paul will face his first pro boxer - after winning his first four pro bouts against Youtube rival AneSonGib, NBA star Nate Robinson, and MMA veterans Ben Askren and Tyron Woodley.

Paul went the distance for the first time back in August, when he won an eight round decision over Woodley. On that same card, Fury won a four round decision over Anthony Taylor.

Fury, the 21-year-old younger brother of WBC heavyweight champion Tyson Fury, will have his older sibling in his corner on fight night.

When they finally meet in the ring next month, Paul intends to execute a game plan to tire Fury out and then stop him in the second half of their eight round encounter.

"I will TKO him in the later rounds. He hasn't had a fight past four rounds so I think he'll be gassed," Paul said.

"I think this will be the first time he's getting punched in the face by someone who can actually hit and is the same weight as him. He's always fought smaller guys with losing records. So I think he's going to fade. I know he's going to fade.

"It's just what round [will I get the knockout]? Fifth? Sixth? Seventh? Maybe I knock him out in the last ten seconds of the eighth. But he's not hearing that eighth bell ring. I've got $500,000 on the line, and when he loses, he has to change his name to Tommy Fumbles."
