Hasim Rahman Jr. believes he will force Jake Paul into retirement after they fight in August.
The pair fight on August 6 when the YouTuber and boxing promoter - and professional boxer - will make his sixth career appearance.
Rahman is the first fighter he faces who can be considered a boxer first and foremost, having previously fought a mixture of social media stars and MMA athletes.
Rahman, the son of former heavyweight champion Hasim Rahman Sr., spoke to The Schmo about his prospects.
"I believe that he's going to retire after this fight, I don't think there's going to be a rematch," Rahman Jr. said.
"When I get through with him, I think given his response and mannerisms after the first Woodley fight, he seemed he was on the verge of not doing this anymore. So when I'm finished with him, I think he's going to completely step away from the sport. Paul is going to fall, man.
"This is it for him, this is it for you, Jacob. It's over for you, it's a wrap. Go ahead and go over to the WWE with your brother. They are two boys from Ohio so they can go ahead and kick it off in the WWE, but this is boxing and this is a real fight. I'm going to punish this boy."
