Thomas 'The Train' Petersen is a Minnesota native and Division I wrestler at heavyweight whose Octagon run has been streaky — a majority-decision win over Guilherme Pat in April 2026 followed by a quick calf-slicer submission loss to Valter Walker in July. Seven of his 11 wins have come by knockout, giving him real power to pair with his wrestling base. He now meets Brazilian debutant Gabriel Lorenço after his original opponent, Alvin Hines, was pulled from the card.
