Fierro (20-1-2, 16 KOs) defends his WBO NABO Lightweight title against Uruguay’s once-beaten Estela (14-1, 9 KOs) in what promises to be an explosive main event. The WBO No.5 rated Fierro is closing in on a coveted world title shot in 2023, but he must first get by the very dangerous Estela, who is coming off a career best win in November over previously undefeated Ruben Torres.
