Brazil’s Vitor Petrino needed just 4 minutes 16 seconds to defeat American heavyweight Austen Lane at UFC Nashville on Saturday, forcing a tap with a rear-naked choke in the first round. The bout marked Petrino’s debut in the heavyweight division after an 11-0 start as a light heavyweight and two subsequent losses. Lane, a former NFL defensive end, fell to 1-4 in his last five UFC appearances, casting doubt on his roster status. Petrino’s emphatic finish re-establishes momentum for the 27-year-old and positions him for a higher-profile matchup in a crowded heavyweight field.
