A 25-year-old American nicknamed 'The Monkey King' scored a rare, 22-second slam KO at UFC Vegas 16

A 25-year-old American nicknamed "The Monkey King" scored a rare knockout at the behind-closed-doors UFC Vegas 16 show Saturday.

It took Jordan Leavitt just 22 seconds to secure the finish, having picked Matt Wiman up before carrying him across the Octagon inside the Apex facility and slamming him head-first to the canvas.

The force from the slam had an instant effect on Wiman who was out cold, with his eyes rolled to the back of his head, and his body stiff.

The fight was over.

"It's crazy," beamed Leavitt after advancing his undefeated pro-MMA record to eight wins (one knockout, five submissions, and two decisions).

"I've never removed anybody from their consciousness before in a fight, that's my first time."

Leavitt continued: "My style is definitely an exhibition of the gentle art, not a lot of that brutish nonsense that I just did I guess.

"Usually, you will see me do a lot more relaxed, flowy jiu-jitsu; nice, harmless front kicks, but today I hit him with the earth. Sometimes that's what happens."

Leavitt's finish earned him a $50,000 performance-related bonus from the UFC, capping a memorable year for the fighter despite the coronavirus pandemic.

It was Leavitt's fourth bout of the year, and he said his wife is pregnant and expecting "a baby girl."

"I got my UFC contract and life is just looking up," he said. "I have nothing to complain about."
