Afterward, he fought for Legacy Fighting Alliance where he got a highlight-reel knockout over David Nuzzo. Following the victory, he earned a spot on Dana White‘s Contender Series 2 when he took on Alfred Khashakyan. After defeating Khashakyan with a stunning knockout in the first round, he was awarded a UFC contract.
  3. On December 1, 2017, he made his Ultimate Fighting Championship (UFC) debut against Terrion Ware at The Ultimate Fighter 26 Finale. He went on to win the fight via unanimous decision.
