Stipe Miocic doesn't remember tapping out, but remembers punching Overeem unconscious

Stipe Miocic just remembers one thing, and that's knocking out Alistair Overeem.
The UFC heavyweight champ, Miocic, successfully completed his first title defense on Saturday night at UFC 203. The Cleveland native knocked out top contender Overeem in the first round of a wild fight. Although it was pretty clear who won the fight, there was a bit of controversy after the fight, as Overeem accused Miocic of tapping out to one of his submissions.
