Premier League fans will face random spot-checks of their Covid-19 status at grounds in the first few matchdays of the season, the league says.
The top flight announced protocols for the new season, saying fans must be prepared to prove they are fully vaccinated or have had a negative lateral flow test in the last 48 hours.
The league is preparing in case it becomes mandatory for all fans to have their coronavirus status checked.
The 2021/2022 season begins on Friday.
Brentford host Arsenal at 20:00 BST in the opening game.
Fans will be able to show their Covid-19 status using the NHS Covid pass through the NHS app or website.
