The two men took the opening minute to work at range before things quickly escalated with some heavy exchanges, one of which ended with Pimblett on the mat before he managed to work back to his feet. "The Baddy" connected with some massive punches of his own as Gaethje continued trying to walk forward, and he also found early success battering his opponent with leg kicks.

Both men broke their respective personal records for strikes landed in a fight during a wild final round, and after 25 incredible minutes of action it was Gaethje who claimed the UFC's interim lightweight belt for the second time.
