YouTube sensation-turned-boxer Jake Paul takes on his toughest opponent to date when he faces Tommy Fury at Diriyah Arena in Diriyah, Saudi Arabia, on Sunday (ESPN+ PPV, 2 p.m. ET).

Paul and Fury originally were scheduled to fight in December 2021, but a rib injury forced Fury out of the bout. Then they were supposed to square off Aug. 6, 2022, but Fury was denied entry into the U.S.

While Fury is seen as the first real boxer Paul (6-0, 4 KOs) will face since he started fighting professionally more than three years ago, Paul is confident he will be victorious and said he and his team have done their homework.

"We've picked this guy apart. We've studied him. He makes a lot of mistakes," Paul said during the final news conference Thursday. "He's great on offense. He's got a great jab. Lots of combos. Speed. Good footwork. Good movement. He's a good boxer, but he's not a great boxer. His lack of defense and lack of head movement is going to be exposed on Sunday."

Fury (8-0, 4 KOs), the younger half-brother of heavyweight champ Tyson Fury, promised a KO victory.

"You're getting put to sleep inside four rounds," Fury said. "... I'm not an old man. I'm a fresh, young fighter. I'm going to put you away. You had two very lucky escapes from this fight. You should have taken those escapes. You should not be sitting here right now because this is bad for you. You should have stuck to making easy money fighting old men and celebrities. I'm coming to take your head off."
