Kevin Lee cracked Gregor Gillespie across the jaw with a right hook and then came across the left side of his face with a vicious left head kick. The kick knocked Gillespie out on his feet and sent him crashing down with his back against the Octagon.
Lee added a hammerfist on a fallen Gillespie for good measure, but he didn't need the extra shot at all. He more than won the fight with the assault that came before it.
Lee's scintillating first-round KO kicked off the pay-per-view portion of UFC 244 at New York's Madison Square Garden on Saturday night.
The instant Knockout of the Year candidate understandably put Twitter into a frenzy.
Holy shittttt!!!! That was absolutely freaking brutal
