Two bleacher packages will be added to the existing seating set-up for the Saul “Canelo” Alvarez-Austin Trout junior middleweight championship on April 20 at the Alamodome in San Antonio, Texas, allowing for additional seating for over 3,000 people, Golden Boy Promotions announced on Friday.

The anticipated 154-pound showdown has already sold approximately 33,000 tickets but there is an extremely high demand for the fight. Newly created seating will be available for purchase at the Alamodome box office on Monday, April 15 at noon CT.

“We are thrilled that the fans have responded in such an incredible fashion to this amazing match-up,” said Golden Boy Promotions President Oscar De La Hoya. “There is no doubt the Alamodome is going to be electric on April 20. I for one can’t wait to be there and it’s clear that tens of thousands of fans can’t wait either.”

Newly released seating priced at $150 and $100, plus applicable taxes, fees and services charges, with a ticket limit of eight per person, will only be available for purchase at the Alamodome box office.

Alvarez-Trout,a scheduled 12-round fight with the vacant RING magazine title on the line, is promoted by Golden Boy Promotions, Canelo Promotions and Leija & Battah Promotions, in association with Greg Cohen Promotions.

The co-main event will be a 10-round fight between undefeated prospects Omar Figueroa Jr., of Weslaco, Texas, and Abner Cotto, of Caguas, Puerto Rico, which is presented in association with Miguel Cotto Promotions.

The fights will air live on Showtime at 10:00 p.m. ET/7:00 p.m. PT.
