The weights are in for Saturday's big rematch. Iván “Iron Boy” Calderón and WBO junior flyweight champion Giovani Segura made weight for their fight at the Auditorio del Estado in Mexicali, Baja California. Calderon (34-1-1, 6KOs) came in at 107-pounds, while Segura (26-1-1, 22KOs) was 108-pounds. Segura stopped Calderon last August. Photos by Joel Colon/PRBBP
