UFC heavyweight Tai Tuivasa suffered a setback at UFC 331. He was knocked out early on. The loss occurred in round one. It followed a troubling 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 was stopped in round one regardless. The first-round defeat came right after his recent move to American Top Team.
