After few exchanges between the fighters in the opening two rounds, Adesanya landed the more decisive blows thereafter. Romero (13-5) has now lost four of his past five fights, including the previous three.

Earlier, Zhang Weili retained the women's strawweight title with a split-decision win against Joanna Jedrzejczyk in a classic, which was regarded as arguably the greatest women's fight in MMA history by many critics of the sport.
