Prior to getting knocked out by Stipe Miocic in the very first round in the main event of UFC 203 in Cleveland, Ohio (see it again here), Alistair Overeem nearly ended the fight with a guillotine choke after flooring the Heavyweight champion with a solid right hand.
In fact, during his post-fight interview, "Reem" was confident in saying he felt a tap, and the fight should have been over, crowning him the new division king. Replays, however, didn't show a tap from Miocic, only a slick escape.
And Stipe firmly denied ever tapping or even coming close to it.
