TAMPA, Fla. – Just as the commentary team was pleading for Dustin Jacoby and Vitor Petrino to close their fight strong at UFC on ESPN 63 , a spectacular highlight arrived. The crowd at Amalie Arena was chanting “boring” as the final 90 seconds in the third round of the light heavyweight bout ticked down. That’s when Jacoby (20-9-1 MMA, 8-6-1 UFC) lined up an absolutely massive straight right hand that instantly knocked Petrino (11-2 MMA, 4-2 UFC) out cold and sent him folding to the canvas at the 3:44 mark of Round 3. It was a finish that woke up everyone in the arena, and you can check out a replay of Jacoby’s handiwork below (via X ): A HOME RUN PUNCH FROM DUSTIN JACOBY #UFCTampa pic.twitter.com/n24Ea2RwUi — ESPN MMA (@espnmma) December 15, 2024 Jacoby came into the fight off a difficult stretch, with one win in his previous five fights.
