Jake Paul's manager Nakisa Bidarian believes Paul's boxing career is on the line ahead of his fight with Nate Diaz on Saturday night live on DAZN and DAZN PPV.
Paul's fight with Diaz is his first since losing to Tommy Fury earlier this year, and a win is imperative for 'The Problem Child' if he is to keep calling out and facing some of combat sport's biggest stars.
"He may retire if he loses to Nate Diaz," Birdarian told ESPN.
"His boxing career is on the line, in terms of being one of the top three or four guys in the entire sport globally.
"I think if he was to lose, he'd just go to being another prospect that's coming up in the ring."
If Paul gets successfully past Diaz this weekend in Diaz, he is likely to have a keen eye on Fury's next matchup against KSI on October 14 live on DAZN, and may look to face the winner.
