BOXING legend Butterbean cast fresh concerns over Mike Tyson heading into the controversial fight against Jake Paul.
The heavyweight icon faces YouTuber-turned-boxer Paul on November 15 in a bout widely slammed over the 30-year age gap.
Now Butterbean - real name Eric Esch - has had his say by claiming Tyson looks out of shape.
He told : "I saw Mike about three weeks ago, and he looked pregnant.
"I would knock him out. He has no chin. The problem with those who have lost to Tyson is they didn’t challenge him."
The £60million fight faced further outrage when Tyson pulled out of the initial July 20 date after suffering an ulcer flare up in his stomach.

He has since been deemed medically fit to continue training and is required to undergo additional brain and hearts tests ahead of his fight.
Paul, 27, has ten wins and only one loss in the boxing ring, losing a 2023 split-decision to Tommy Fury, 25.
Tyson meanwhile returns for his first pro fight since 2005 despite facing Roy Jones Jr in an exhibition bout in 2020.
During Tyson's reign of dominance, Butterbean became a fans' favourite during the 1990s for his run of knockouts.

During the height of his career he weighed as much as 36 STONE and only ever went past the fourth round once - against the great Larry Holmes.
His last boxing bout was in 2013 but Butterbean has teased a comeback in recent years having lost a stunning 14 STONE.
He dropped the huge amount of weight after starring in a TV show alongside former wrestler Diamond Dallas Page.
Butterbean had 91 boxing bouts - compared to just the 11 of Paul who he recently called out to a $1.5m winner-take-all bout.
