Former UFC champion Tyron Woodley is promising to end the boxing run of Jake Paul, when they collide this coming Sunday, in the main event of a Showtime Pay-Per-View card.

Woodley is the toughest opponent of Paul's short boxing career.

The Youbtube star has racked in three wins with all three ending inside the distance. 

Paul, 24-years-old, stopped Youtube rival AnEsonGib in one round, ex-NBA star Nate Robinson in two, and retired UFC fighter Ben Askren in one this past April.

The 39-year-old Woodley, who at one time was one of the best MMA fighters in the world, is not just coming for a check.

“I’m just glad to be a part of it, but I’m not only here to participate. I’m here to f------ take over. And you’re going to see Jake Paul get hurt in a way you’d never imagine. He may not want to do this again after this,” Woodley told MMA Fighting.

Woodley has been training very hard for his boxing debut.

"When you see the destruction and the f------ training and the mentality and the coaching and the running every single day, all different terrains, hills, speeds, adjustments, altitudes, it’s going to be too late for him to back out of this fight. And that’s why in the beginning I said I wanted a ‘no bitch out’ clause," Woodley said.

"Because I knew if he saw how hard I really punch, and how great my mind really is for this sport — any combat sport — my IQ and just the coaches, [Paul might back out]."

“It’s too late. He’s going to be the biggest bitch in the industry of female dogs if he backs out of this fight now. So now I can talk for real. Now I can say what we really were doing. Now I can show you guys. I promise you, it’s going to be internet breaking. This entire camp has been a movie. If he tried to pull a Covid-19 [and pull out now], I’m coming to his hotel and I’m sticking a Q-tip in his nose and I’m going to do it for seven tests. I want to see some x-rays. I want to see some ultrasound. I want the doctor to produce the [positive test] to me personally."
