Sean Sharaf delivered one of the biggest upsets in UFC history on September 20, knocking out Olympic gold medallist Gable Steveson with a left hook just 12 seconds into their heavyweight bout at UFC 331 in Los Angeles. Steveson, the undefeated prospect and two-time NCAA champion, was a minus-2400 betting favorite. The knockout was the third-fastest finish in UFC heavyweight history and ended Steveson’s perfect 4-0 MMA record.

The knockout that shocked the sport

Steveson opened with a leg kick but immediately retreated, extending his arms to parry punches. Sharaf, 33, threw a right hand followed by a devastating left hook that connected cleanly on Steveson’s chin. The 26-year-old went stiff on the canvas as referee Frank Trigg waved off the fight. Lead commentator Jon Anik called it the “stunner of all stunners” while Joe Rogan said, “Oh my goodness, the way his head snapped back, he’s out cold.” Steveson walked out of the octagon on his own accord but was greeted by boos from the crowd.

A massive betting upset

Sharaf entered the bout as a plus-2500 underdog with bookmakers, meaning a $100 bet on him would have paid $2,500. Steveson was the overwhelming favorite at minus-2400 odds. Sharaf earned $100,000 in bonuses for the knockout victory. The former U.S. Marine had struggled in the UFC, losing his first two fights by knockout before this stunning win.

Steveson’s fall from hype

Steveson won Olympic gold in freestyle wrestling at the 2020 Tokyo Games and captured back-to-back NCAA Division I national championships in 2021 and 2022. He made his UFC debut in July with a first-round knockout of Elisha Ellison, entering Saturday’s fight undefeated at 4-0. Jon Jones, the octagon legend and Steveson’s mentor, watched ringside as his protege was knocked out. Steveson had been projected as a future title contender before this loss.

Sharaf’s vindication

Sharaf spent fight week telling anyone who would listen that he would defeat Steveson despite the long odds. After the knockout, he told Joe Rogan, “I’m not surprised, motherf***ers. I worked so hard, I prayed so hard, I believed in myself when nobody believed in me.” The Santa Ana native improved his record to 5-2 with his first UFC victory at the third attempt. His previous two UFC fights ended in second-round knockouts.

Final Thoughts

Steveson’s loss ends his undefeated run and forces a reset on one of MMA’s most hyped prospects. The 12-second knockout ranks among the sport’s greatest upsets and serves as a stark reminder that betting favorites and hype trains can collapse in an instant.
