Liverpool’s Liam Smith and Canelo Alvarez fight for the WBO light-middleweight title, this weekend, with Smith’s light-middleweight title on the line, too.
The pair face each other at the AT&T Stadium in Arlington, just outside of Dallas, Texas.
The stunning stadium is home to NFL giants Dallas Cowboys and has an official capacity of 80,000 for American football.
But the record attendance at the arena was for the 2010 All-Star NBA game which was watched by 108,713 fans.
The stadium – which took four years and cost almost £1bn to build – has hosted boxing twice before with Manny Pacquiao involved in both.
The Filipino star fought Joshua Clottey and Antonio Margarito there in 2010.
The stadium could have almost 50,000 in there when Smith and Alvarez go toe-to-toe.
Smith’s WBO light-middleweight title is on the line on Saturday night.
The Liverpool fighter won the belt last year with a seventh-round stoppage of American John Thompson in Manchester.
He has since made two defences of the title but is making a big step up in class against Alvarez, who previously held the WBC middleweight title.
The Mexican has moved back down to light-middleweight where he was once WBC and WBA champion.
