Jake Paul is currently suffering from memory loss and has been told to ‘not do boxing’ by a doctor.
The YouTuber is currently 4-0 in his professional fighting career but it’s given him brain trauma at a young age.
Paul played football as a child and he claims the last two years of boxing have left more of a lasting impact.
He told Graham Bensinger on his YouTube channel: “I got my brain scanned right before I started boxing and the doctor told me there’s lack of blood flow from the concussions I had playing football to certain areas on my brain.
“One of them I believe is the frontal lobe which is partial for memory and so on.
“After my first year of boxing, I went back and it was worse.”
The 24-year-old then said his brain is so damaged already, doctors have told him to stay away from the ring despite his young age.
He added: “[The doctors] advice is don’t do that sport.
“That’s all they can advise as a doctor, I think before it was affecting me at a rapid pace because I never took it easy.
“I was always thrown in there with people who were way better than me until I started to slowly get to their level.”
Paul went on to confess his short-term memory has taken a hit and he also slurs every ‘100th word or so’ in conversation.
He returns to the ring on Saturday night against Tyron Woodley, who he defeated via split decision in August.
‘The Problem Child’ was set to face long-time rival Tommy Fury in a massive grudge match in Miami.
However, Fury pulled out of the fight last week after suffering a broken rib and bacterial chest infection.
Woodley stepped in at the last minute after training non-stop for a rematch with Paul.
Both men will take part in the final weigh-ins on Friday before clashing at the Amalie Arena.
