Jake Paul will fight pro boxer Andre August in a return to action on 15 December in Florida.
Paul, 26, is 7-1 in his fighting career and says he still harbours ambitions to be a world champion.
“I want to build my experience in the ring against seasoned fighters,” Paul said.
August, 35, has 10 wins and one loss on his record and will fight fellow American Paul in a cruiserweight bout over eight rounds.
“I don’t talk very much. I’m all about that action. Jake Paul has the money, the fame, the team and the resources, but he doesn’t have my hunger,” August said.
“When that bell rings, I am going to go straight to Jake Paul and ring his bell and send him back to YouTube for good.”
In the co-main event in Orlando, American Shadasia Green will face Franchon Crews-Dezurn for the vacant WBC super-middleweight title.
Briton Savannah Marshall beat Crews-Dezurn earlier this year to claim the undisputed super-middleweight championship, but injury forced her to relinquish the WBC title.
Green, 34, is undefeated in 13 fights while 36-year-old Crews-Dezurn is the former undisputed champion and has only lost to Marshall and Claressa Shields.
