Thomas Petersen produced a late finish at UFC Vegas 124, knocking out Gabriel Lorenzo in the closing seconds of the third round after a fight that swung back and forth.
Lorenzo came close to ending the bout in the first round, putting Petersen in trouble early. Petersen hit back in the second, nearly finishing Lorenzo himself before the fight went to the third. The knockout came with the clock almost out, a result that kept Petersen from the scorecards and denied Lorenzo a debut win.
Petersen, a 31-year-old southpaw from the United States who trains at Spartan MMA, now stands at 12-5 once this result is added to his 11-5 record. Nicknamed The Train, he stands six-foot-one with a 74-inch reach. His numbers show an accurate striker, landing 3.1 significant strikes per minute at 59 percent accuracy, and he averages 3.01 takedowns per 15 minutes.
His recent form has been uneven, matching the pattern of alternating wins and losses over his last nine fights across three years. His most recent recorded fight before this one was a first-round submission loss to Valter Walker in July 2026. Before that, he won a majority decision over Guilherme Pat in April 2026, and he was knocked out by Vitor Petrino in the third round in October 2025. Sunday's knockout continues the up-and-down run, with a win following the Walker loss.
For Lorenzo, the defeat was a difficult introduction to the UFC. He arrived on an eight-fight winning streak, which the stoppage ended in his promotional debut.
Why it matters
- Lorenzo's eight-fight winning streak ends in his first UFC appearance, a stoppage that came with only seconds left in the fight.
- Petersen's alternating pattern of results continues, and he has now won a fight that was close to being taken from him in the opening round.
- The late finish also sidesteps the judges in a bout that had momentum swings in each of the first two rounds.
The result adds a notable knockout to Petersen's record and gives him a win after the first-round submission loss to Walker.
