YouTube star turned boxer Jake Paul highly doubts that a potential fight with Floyd Mayweather will ever happen in the future.

Last month, Mayweather took part in an eight round exhibition fight with older brother Logan Paul.

Due to the tremendous disparity in height and weight, the 44-year-old Mayweather had some unexpected trouble during the bout and the contest would end up going the full distance.

But a few weeks before that contest took place - Jake Paul and Mayweather created headlines when they tussled at a press conference in Florida. Their confrontation exploded when Paul stole Mayweather's hat - which led to both teams getting involved and punches being thrown.

Many observers felt the confrontation was orchestrated to set the stage for a fight between the two of them in the future.

Paul (3-0, 3 KOs) made it clear that he would only fight Mayweather under the rules of a sanctioned fight.

However, Mayweather is not willing to give up the size advantage this time around.

He wants Paul to squeeze down to at least the junior middleweight limit of 154. 

“Jake Paul talked about me and him fighting in a real fight,” Mayweather told Rob Moore back in June. “If it’s a real fight, then I’ll go down to my real fighting weight class, which is 147 pounds or 154 pounds. If Jake Paul can come down to 154 pounds, then we can see his skills.”

Because of the difference in weight, Paul is not expecting that fight to ever come off.

“I don’t think it’ll happen,” Paul told Dexerto. “He wants me to cut down to 147 pounds, and then he’ll fight me. So, before he fought my brother, we were ‘fake fighters.’ And now, he will only fight Jake Paul if I cut to 147 pounds, which is physically impossible for me to cut that much.”

Paul will return to the ring on August 29th, when he faces former UFC champion Tyron Woodley in the main event of a Showtime Pay-Per-View card. That bout is scheduled for a catch-weight of 190 pounds.
