In the second most important event of the event, the reigning UFC strawweight champion, Weili Zhang, will defend her title against the fourth-ranked Amanda Lemos.
Title confrontations were officially announced by representatives of the organization.
Aljamain Sterling, 33, made his third successful defense of his title ten days ago, winning a five-round split decision over Henry Cejudo, and 28-year-old Sean O’Malley defeated former division champion Petr Yan in the last fight by a split decision.
Weili Zhang, 33, regained her UFC championship belt last November with a second-round rear naked choke finish against Carl Esparza, while Amanda Lemos, 35, pulled off two consecutive knockout victories, dispatching Michelle Waterson and Marina Rodriguez.
