LAS VEGAS — The final figures will come officially from the Nevada State Athletic Commission in due time.

For now, however, the card headlined Saturday night by Canelo Alvarez and Terence Crawford drew the second-highest announced attendance for an indoor boxing show in U.S. history. The capacity crowd at the Las Vegas Raiders’ Allegiant Stadium was announced at 70,482.

It is not yet clear how much of that impressive figure accounted for tickets sold.

Alvarez’s TKO victory over Billy Joe Saunders established the U.S. indoor record for tickets sold and announced attendance in May 2021 at AT&T Stadium in Arlington, Texas. The Texas Department of Licensing & Regulation confirmed that 66,065 tickets were sold to that event and an additional 989 tickets were given away.

The total fan attendance for the Alvarez-Saunders show was 67,054. Matchroom Boxing, the promoter of that card, announced the attendance as 73,126 on fight night, but that figure included every employee working the event, in addition to fans who paid for their tickets.

Regardless, the paid attendance for Alvarez-Saunders surpassed the longstanding mark established by the Muhammad Ali-Leon Spinks heavyweight championship rematch in September 1978. The crowd for that bout at Louisiana Superdome in New Orleans was announced at 63,352.

Several cards held outdoors in the U.S. have attracted larger announced crowds than the Alvarez-Saunders and Alvarez-Crawford shows.

Crawford (42-0, 31 KOs), of Omaha, Nebraska, outboxed Mexico’s Alvarez (63-3-2, 39 KOs), won a unanimous decision and became a world champion in a fifth division and an undisputed champion in a third weight class. He won The Ring, IBF, WBA, WBC and WBO super middleweight titles from the favored Alvarez.

The Alvarez-Crawford card was the first boxing event held at Allegiant, which opened prior to the 2020 NFL season.

Alvarez, who has been boxing’s biggest draw in the U.S. for much of his career, fought at a stadium in Las Vegas for the first time.

Each of his previous five fights in Las Vegas were held at nearby T-Mobile Arena, where he has headlined 10 times overall in the past nine years. Alvarez, 35, also boxed eight times at MGM Grand Garden Arena in Las Vegas.
