Masvidal (34-13) ran right at Askren (19-1) to open the bout and landed a flying knee flush on the chin of Askren, who immediately stiffened up before dropping to the canvas. Masvidal landed a couple of more strikes on the ground, but Askren appeared to already be out cold.
Masvidal got down on all fours next to Askren right after the KO when Askren was unconscious and taunted him, slapping the ground. A few seconds later, he did some more taunting, dropping to the mat stiff to make fun of Askren.
Askren remained on the canvas for several minutes and still appeared dazed when he finally stood up and left the Octagon with his team.
Asked why he decided to try a flying knee to start, Masvidal responded, “Because he’s a bum.”
“I had to show him that there’s consequences sometimes,” he said.
Duane Ludwig held the previous UFC record for fastest knockout at 6 seconds against Jonathan Goulet in 2006.
