ESPN reported about the organization of the title fight.
Valentina Shevchenko, 34, made her seventh successful title defense last June, defeating Taila Santos by split decision in five rounds, while Alexa Grasso, 29, is on a four-fight streak, defeating Vivian Araujo in her last fight by unanimous decision.
Recall that the main event of the UFC 285 tournament will be a fight for the vacant UFC heavyweight title between Jon Jones and Cyril Gan.
