Justin Gaethje did it again.

The lightweight division’s human highlight reel needed less than a round to knock out Edson Barboza on Saturday night, downing Barboza with a monstrous right hand in the main event of UFC Philadelphia. The win gave Gaethje back-to-back first-round knockouts following his similar destruction of James Vick, and thurst the former WSOF champion back into the title picture at 155 pounds.

Check out reaction to Gaethje’s handiwork below, plus the best of the rest from a roller-coaster night at UFC Philadelphia.
