Stipe Miocic is finally opening up about that devastating loss to Francis Ngannou over the weekend -- assuring everyone he's okay and vowing to return as a better fighter.
Stipe did not participate in any post-fight interviews following his loss to Ngannou in the main event at UFC 260 on Saturday night ... where the heavyweight champ was knocked out cold 52 seconds into the 2nd round.
Ngannou smashed Stipe with a brutal left, sending Stipe crashing to the ground in an awkward fashion -- you could see his knees buckled and folded under him.
