Tate won in the fifth round by submission via rear naked choke becoming the UFC Women's Bantamweight Champion.

After Ngannou lost his first title bout against Stipe Miocic at UFC 220, he left his original gym at MMA Factory in France to move to the United States to train under Nicksick at Xtreme Couture.
During the fight Nicksick told Strickland that he needed to keep the pressure and pace on Adesanya regardless of the signs they were winning.
