Fans attending New Orleans Saints home games will be required to show proof of vaccination or a negative COVID-19 PCR (polymerase chain reaction) test from the previous 72 hours, according to a new mandate announced Thursday by New Orleans Mayor LaToya Cantrell.

Fans will also be required to wear masks when they aren’t eating or drinking. However, the city and the Saints are still allowing full attendance inside the Caesars Superdome.

“We are not limiting capacity. We’ve got to get our people vaccinated,” said Cantrell, who pointed to rises in COVID-19 cases and hospitalizations throughout the state of Louisiana.

New Orleans is believed to be the first NFL city to have such a mandate in place for fans attending games — starting with the Saints’ second preseason game against the Jacksonville Jaguars on Monday, Aug. 23.

Both the Saints and the NFL released statements that began by stressing that their top priority remains the health and safety of fans and everyone associated with the game.

New Orleans’ mandate also covers bars, restaurants, breweries, gyms, fitness centers, sports complexes, concerts, event spaces, casinos and racetracks, among other venues. New Orleans also recently canceled its popular Jazz & Heritage Festival, which had been rescheduled for October. But Cantrell stressed that she is not in favor of a “shutdown.”
