In one of the most devastating knockouts in the history of the UFC, Gregory Rodrigues put out the lights of Jack Hermansson, scoring the first-round finish in the featured prelim bout of UFC 317.

Hermansson got on the attack early, working low kicks and combinations as he placed a small cut on Rodrigues. Rodrigues looked to pressure back, however, and showed his power in his punches.
