Premiership leaders Rangers have told their supporters that proof of Covid vaccination status is required for this weekend's home clash against Hibs.
The controversial proposals from the Scottish Government mean clubs with home attendances of 10,000 or more must provide a "reasonable number" of checks at the turnstiles.
It was thought earlier this week that a 'grace period' to allow clubs to prepare for the new rules would mean a more lenient approach for the next two weeks.
But this morning Hearts confirmed they will still be refusing entry to anyone who cannot produce a certificate when asked.
Rangers have now admitted they will be doing the same while Aberdeen vs Celtic is another fixture that will lie over the 10k threshold.
In a statement, the champions said: "Ahead of Sunday’s Scottish Premiership match against Hibernian, we once again highlight the introduction of vaccine certificate checks across Scotland.
"Sunday’s game is a 'test event' and thus, we are required by law, to carry out the same procedures as when the 'grace period' is over.
"For the avoidance of doubt, following legislation introduced by the Scottish Government, everyone attending matches at Ibrox Stadium must be fully vaccinated and everyone must bring proof of this status with you to the match, unless exempt.
"Those exempt for medical reasons or due to participation in vaccine trials are asked to carry an official letter to confirm this."
