Saúl “Canelo” Álvarez defends his undisputed super‑middleweight crown with all four major belts and The Ring title on the line at Allegiant Stadium. The event is available only on Netflix worldwide for subscribers with no pay‑per‑view fee, and Mexican broadcasters do not have rights. Published schedules vary by outlet: TN lists a 22:00 start in Argentina with the main event near midnight, while Mediotiempo reports prelims at 17:30, main card at 19:00 and the headliner around 21:00. Undercard bouts reported include Callum Walsh vs. Fernando Vargas Jr., Christian Mbilli vs. Lester Martínez and Mohammed Alakel vs. John Ornelas. Terence Crawford moves up two weight classes, and Mediotiempo notes a victory would make him the first male of the four‑belt era to be undisputed in three divisions in one night.
