0-2 Sharaf stuns unbeaten Steveson with 12-second KO at UFC 331 as Jones watches on

Sean Sharaf delivered one of the most shocking upsets in recent UFC history, knocking out Gable Steveson in just 12 seconds at UFC 331 at Crypto.com Arena in Los Angeles. Sharaf, who entered the fight with an 0-2 record in the promotion, landed a clean left hook early in the opening round to put the previously unbeaten Steveson to sleep.

Steveson had arrived at the bout riding a 4-0 professional record and was installed as a heavy betting favourite. Sharaf, by contrast, had yet to register a win inside the Octagon, making the outcome one of the starkest mismatches-on-paper to produce such a swift reversal.

Ringside for the finish was Jon Jones, the former two-division UFC champion and Steveson’s mentor. Footage of Jones’s reaction to the knockout has spread widely online, with the heavyweight great appearing to mouth “Oh, my God!” as he turned to his fellow cornermen in disbelief.

In the build-up to the fight, Steveson had been openly dismissive of Sharaf, framing the matchup as little more than a stepping stone toward a title shot. At the pre-fight press conference, Steveson went further, provoking Sharaf by raising past controversies that have made the Olympian a polarising figure among fans and fighters alike. The outcome rendered that confidence spectacularly misplaced.

The loss is the first of Steveson’s professional MMA career and raises immediate questions about the trajectory of a fighter who arrived in the sport with considerable hype, buoyed by his decorated wrestling background and his association with Jones.
