Texas, Dallas officially holds the record for the biggest U.S. indoor event in boxing history.
Despite a global pandemic ongoing, the AT&T Stadium - home to NFL's Dallas Cowboys - was able to cram in 73,126 fans into the venue for Canelo Alvarez's victory over Billy Joe Saunders.
In doing so, it beat the previous record set by Muhammad Ali and Leon Spinks in their 1978 rematch at the Superdome, New Orleans with 63,352 present at the time.
An initial 60,000 were expected at the super middleweight unification showdown but due to popular demand, some 13,126 tickets were added.
Canelo forced Saunders to retire on the stool after round eight and broke his cheekbone, as confirmed by the British fighter.
Canelo, a four-division world champion, is expected to face Caleb Planet next for all four major belts - the first time at 168 pounds in boxing history.
