The WBA on Tuesday ordered a fight between Amanda Serrano and Erika Cruz for the undisputed featherweight title, according to the organization's Twitter account.
The sides will have 30 days to close a deal before a purse bid is ordered.
Serrano (43-2-1, 30 KOs) holds the WBO, WBA and IBF titles at 126 pounds while Cruz (15-1, 3 KOs) holds the WBA version.
Serrano, 32, met Katie Taylor in the biggest boxing match in women's history in April and dropped a split decision. That fight was at 135 pounds for the undisputed lightweight championship. Afterward, Serrano returned to 126 pounds and successfully defended her three titles with a unanimous-decision victory over Sarah Mahfoud in September.
Cruz, 32, won the featherweight title in 2021 with a technical decision over Jelena Mrdjenovich and has made two defenses. Most recently, she scored a shutout decision over Mrdjenovich in a September rematch.
Serrano is ESPN's No. 1 featherweight and No. 3 pound-for-pound boxer. Cruz is No. 2 at 126 pounds.
Taylor retained her lightweight championship on Saturday with a unanimous-decision over Karen Elizabeth Carbajal and called for a rematch with Serrano next year in Taylor's native Ireland.
