Watch fighter Justin Watson produce ‘fastest knockout EVER’ with just one punch in Bare Knuckle Fighting Championship

BARE-KNUCKLE boxer Justin Watson produced what's been described as the "fastest knockout" in combat sports history.

The Warmonger locked horns with Cole Ferrell on a stacked BKFC 69 card in Atlanta, Georgia, early on Saturday morning.

But their featherweight showdown lasted the blink of an eye as Watson took Ferrell out with a single punch.

Waston separated his opponent from consciousness with a hellacious overhand right that you would have missed if you'd blinked.

The stunning KO came in at staggering 2.9 seconds and, understandably, went viral.

One stunned viewer of the knockout wrote on X along with the famous 'Friday' meme: "Damn."

Another said: "[That's] insane."

And another said: "Holy s**t."

One remarked: "Me clocking out of work the first second possible."

Another chimed in: "You can make the argument that is a 1.30 seconds KO."

Watson's incredibly quick night at the office even drew a reaction from BKFC co-owner and UFC superstar Conor McGregor.

The Notorious shared a video of Watson's wicked shot to his Instagram story and wrote: "The world's fastest KO! Wow!"

It's not been verified yet, but Watson's knockout is a strong contender to be the fastest in combat sports history.

It has, however, been confirmed as the quickest in BKFC's six-year history.

The fastest recorded knockout in boxing is Mike Collins' four-second stoppage of Pat Brownson back in 1947.

The fastest KO in MMA history is owned by Luis Hernandez, who brutally stopped Brian Topp in three seconds in their Titan FC 83 bout in July 2024.

Jorge Masvidal is the owner of the fastest KO in UFC history, with his viral flying knee stoppage of Ben Askren coming at just five seconds of their UFC 239 in July 2019.

Watson produced a celebration worthy of the KO, performing a cutting-throat gesture before cupping his hands to his ears.

And he was proud as punch of his night's work.
