The flyweight division takes center stage on Saturday, October 10th at the Wintrust Arena in Chicago as Mexico’s Ricardo “El Niño” Sandoval puts his WBC / WBA unified championship on the line in against undefeated minimumweight champion Oscar Collazo, with the action broadcasting live worldwide on DAZN. Sandoval (27-2, 18 KOs) enters this fight ain his boxing prime. The Mexican warrior reached the summit last July after traveling to Japan and dethroning Kenshiro Teraji on his home turf. Coming in as the favorite thanks to his natural height, reach, and power advantages at 112 pounds, Sandoval aims to prove he remains the man to beat in the division. It won’t be an easy night, however, as standing in his way is Óscar “El Pupilo” Collazo. The Puerto Rican star, a WBO/WBA champion at 105 pounds, is making a daring jump up two weight classes to etch his name into the history books of boxing. He is moving up in weight after attempts to make a big fight at minimumweght fell through. Collazo relies on his speed, refined technique, and sharp precision to offset Sandoval’s physical strength in what promises to be an action-packed tactical battle full of explosive combinations. Collazo enters the ring with an unbeaten record of 15-0 (12 KOs).
