Watch Yuneisy Duben deliver incredible one-punch knockout on Contender Series

Yuneisy Duben is about to get a UFC contract.

On Tuesday evening, Duben faced Shannon Clark in the first women’s fight of season eight of Contender Series and she took the opportunity to deliver one of the best knockouts in the history of the show, flattening Clark in the very first round.

Duben was a massive +800 underdog coming into this matchup of unbeaten prospects but she certainly didn’t look it as the Venezuelan fighter lit Clark up with combinations right from the start. Clark couldn’t figure out the range and continued to charge in on Duben, which ended in disaster for her as Duben stepped in with an overhand right that shut off the lights in violent fashion. The sensational knockout makes Duben the biggest underdog to ever win on Contender Series and almost certainly guarantees her a UFC contract.
