Miocic joined the guys on the "TMZ Sports" TV show (airs Monday night on FS1) -- and was asked how he felt about Jon essentially calling him out on social media.
FYI, Jon tweeted after Stipe beat Alistair Overeem at UFC 203 ... "I'm starting to realize the hype is real with that guy. He's legit, it would be the challenge of a lifetime."
Stipe heard the challenge -- but didn't respond with the vitriol of Daniel Cormier. Instead, he praised Jones ... and essentially welcomed Dana White to make it happen.
There's A LOT more in the full interview, which airs tonight on FS1.
