If you're expecting CM Punk to embarrass himself in the Octagon, you're in for a big disappointment -- so says UFC champ Stipe Miocic.
"He's not some guy who's gonna walk in there and drop an egg," Miocic tells TMZ Sports.
"He's gonna go out there ... I think ... he's gonna prove a lot of people that hes worthy."
Stipe says he's pumped to have Punk fighting on the card at UFC 203 -- especially because he knows Punk's a big draw ... and more viewers means more $$$$.
