Jake Paul‘s admittedly nervous for his upcoming tilt with Gervonta Davis, but he tells TMZ Sports he’s got a bit of a secret weapon in his corner to help him make sure he’s ready — Shakur Stevenson!

The YouTuber-turned-superstar-fighter revealed to us on Wednesday that Stevenson — who’s had his share of beef with Davis over the years — is slated to meet with him in just a few days to give him an assist in the ring.

Paul said the two will spar — and he’s hoping it’ll get him as prepared as possible for Tank.

Paul also let us know he’s got a few other famed pugilists — Raymond Ford and Montana Love — working to prime his fists for the massive Nov. 14 bout as well.

Jake, though, did confess he’s still losing some sleep over the upcoming matchup … admitting, “Internally, I’m the most scared going into a fight that I’ve actually ever been.”

“Being vulnerable for a second,” Paul said, “this is crazy. This is scary. It’s kind of keeping me up at night.”

Paul did say he’s got a game plan — one that involves him trying to shed muscle so he can be fast enough for the smaller Davis. He also said he’s working on a way to “walk Tank into a knockout like I’ve done with other opponents.”
