The YouTube star was initially set to face heavyweight legend Tyson in July, but his bout with the 58-year-old has been rescheduled for November 15.
Paul bulked on weight to near 230lbs for the planned clash, and is expected to pile on the pounds again in time for their showdown.
His rival Tyson decided to mock him for his increased weight, suggesting he needed to lose it before their fight.
But Paul has insisted it will benefit him, just like it has during the boxing career of successful current heavyweight Tyson Fury.

He responded on his podcast: “It’s peak male performance bod, and that is fat.
“I mean look at Tyson Fury for example. He is just a big old milk jug and look what he’s done.”
Paul’s maximum weight that he has stepped on the scales for a professional fight is around the 200lbs mark [cruiserweight].
But he could well go beyond that and weigh his career-high mark, in a bid to match the size of natural heavyweight Tyson.
