Supporters will be subject to additional bag searches upon entering Hampden Park
The Scottish FA says extra security will be in place for Scotland's World Cup qualifier with England at Hampden on Saturday after recent terror attacks in Manchester and London.
They've also asked permission to hold a minute's silence before the match. Bag and body searches will be in place as fans approach the national stadium in Glasgow.
"The safety of fans is of paramount importance to the Scottish FA and a range of measures will be implemented as part of an enhanced security operation," Scottish football's governing body say in a statement.
"These increased security measures at Hampden Park [...] may result in delays in entering the stadium.
"To accommodate these increased measures, gates will now open at 3pm, half an hour earlier than originally planned.
"Fans are reminded that the match is sold out and are therefore encouraged to arrive early to ensure that they are in their seats for kick-off."
The game gets underway at 5pm.
The Scottish FA said that the minute's silence will be observed to "pay tribute to the victims of the recent terrorism atrocities in Manchester and London."
