UFC heavyweight Tai Tuivasa suffered a defeat at UFC 331. He got stopped in the opening minutes. The loss happened in round one. It came after a difficult seven-fight losing streak. He had just moved to American Top Team. Tuivasa changed teams because he hoped to take advice from new trainers and change his fight preparation.

He trained alongside heavyweight Francis Ngannou for UFC 331. He spent several sessions with Ngannou during camp. But Tuivasa got finished in round one regardless. The first-round defeat came right after his switch to American Top Team.
