If Stipe Miocic is SERIOUS about a boxing match with Tyson Fury, the Gypsy King says he'll gladly ACCEPT ... as long as they can book it AFTER his rematch with Deontay Wilder.
Of course, Stipe is the reigning UFC heavyweight champ -- but he's so confident in his striking ability, he recently said he'd be down to fight Fury in a boxing match.
So, Fury -- never one to back down -- responded to Miocic ... and he's ALL THE WAY DOWN!
"Stipe says he wants to box me, that would be a good fight for sure," Fury told MTK Global .
