CANELO ALVAREZ and Billy Joe Saunders are on course to sell out the full 60,000 capacity at the Dallas Cowboys Stadium.
Canelo unifies his WBA and WBC belts with Saunders' WBO crown on May 8 in Texas.
With no coronavirus restrictions, promoter Eddie Hearn revealed plans to pack out the place, with 60,000 tickets almost sold.
Hearn told Yahoo Sports: “We got another six or seven thousand to go, and thankfully, we were allowed 80,000 for the Dallas Cowboys Stadium, so we’re going to be at full capacity."
Saunders, 31, is already in America training for the fight, and visited the UFC's Performance Institute.
There, himself and Hearn were pictured with UFC president Dana White, an avid boxing fan.
Saunders comes into the fight having boxed just once in the last 12 months, retiring Martin Murray, 38, in a title defence.
Canelo on the other hand is preparing for his third, having won the belts against Callum Smith, 30, in December, before beating Avni Yildirim, 29, two months ago.
But the Mexican superstar, 30, is admittedly gearing up for a whole new challenge in Saunders, who is unbeaten in 30 fights.
Canelo said: “He moves really well, he’s fast, he knows how to box, and that’s why I’m training.

"That’s why I’m training, I know how to deal with that. I know it’s going to be a difficult fight, especially in the first rounds, and I’m getting ready for that.
“Yes, it’s different; you have to work the fight differently, and you have to be patient.
“You have to wait around round by round, but you also have to win them.
“And you can get them in the first round, eighth round, or the tenth rounds, but I’m not the same fighter I was in 2014.
“I have more experience, and I think that’ll benefit me.”
