BUFFALO, N.Y. (AP) — Buffalo Bills and Sabres fans will have to show proof they’ve been vaccinated against COVID-19 if they want to attend games, Erie County Executive Mark Poloncarz announced Tuesday.

“Our goal is to have a 100% full house for the Bills and the Sabres starting in the fall,” Poloncarz said during a daily briefing.

“Our plan is that unless you are vaccinated you will not have entry to the stadium. It is easy. It is safe,” he said.

Ticket-holders entering Highmark Stadium for NFL games or the KeyBank Center for NHL games will be asked to show digital proof they are fully vaccinated using New York state’s Excelsior Pass cellphone app. Both venues are owned by Erie County.

There will be no religious or other exemptions.

“There’s no God-given right to attend a football game,” Poloncarz said.

The Buffalo Sabres announced last month that fans could attend games in April if they provided proof of vaccination or a recent negative COVID-19 test result.

Erie County’s vaccination rule won’t affect the remainder of the Sabres’ current season.
