Youtube star turned boxer, Jake Paul, has issued a warning to former foe Tommy Fury - advising him that KSI is attempting to weight drain him.

KSI won a close, and some felt controversial, decision over Jake's older brother Logan Paul in 2019.

Last week, Fury and KSI were involved in a weight dispute for their potential fight. Fury wanted a weight limit of 185-pounds, but KSI was standing firm on a weight of 180, which he claimed was agreed-upon.

They were able to reach an agreement on the weight, but it's unknown what the weight limit will be.

Paul believes KSI tries to gain every possible advantage over his opponents.

"Tommy, I'm going to teach you a little something here. KSI is a bitch, he's all f------ talk. He fought Logan at 193lb but wants to weight drain everybody. He says, 'Oh, I'm levels above everybody' but then wants everybody to cut down to get them to as low as possible so that he can take advantage of them," Paul stated.

"It's not going to happen, he's all talk, he only wants to fight disabled video gamers or guys who are f------ old and f------ elbow them in the face."

Back in February, Paul lost an eight round decision to Fury in Saudi Arabia.

There was talk of a rematch, but Paul will first collide with MMA veteran Nate Diaz on August 5th in Texas.

Should Paul prevail, he wants to face Fury in a rematch in the month of October.

"Tommy as my son, I'm disappointed in you, man. I made you a millionaire, I made you famous. You haven't said thank you. You're a pr!ck, you're a bitch, you said you would wipe me across the floor, wipe me across the canvas. But you're the one that tasted the chance, you're the one that tasted the floor in a split-decision you barely beat me," Paul said.

"So after I knock out Nate Diaz, August 5th, I'm coming for you Tommy. You better be ready, I'm coming."
