The Scottish FA and SPFL have confirmed that all professional matches will be postponed this weekend. That includes matches in the four SPFL divisions, the Lowland and Highland League and SWPL1 and 2.
Hibs were scheduled to face Dundee United at Tannadice in the cinch Premiership on Saturday, with Hearts due to host St Mirren on Sunday. But with a period of national mourning across the United Kingdom now underway, a full shutdown has been confirmed.
This weekend's Premier League, English Football League and Women's Super League fixtures have also been called off. The Irish FA has also announced that all football in Northern Ireland scheduled for this weekend will not take place. Scottish Rugby has suspended all "competitive" domestic games this weekend and Musselburgh racecourse has abandoned fixtures scheduled for Saturday and Sunday.?
A statement released by the SPFL read: "Following meetings this morning, the Scottish FA, Scottish Professional Football League, Scottish Women's Premier League, and Scottish Highland and Lowland Football Leagues have agreed that all professional football matches will be postponed this weekend as a mark of respect following the passing of Her Majesty Queen Elizabeth II.
"This postponement will also incorporate the Women's Scottish Cup fixtures this weekend."
Rod Petrie, the Scottish FA president, explained: "We spoke with our counterparts across the UK this morning and in discussions with our colleagues across the professional game in Scotland it was agreed that this was the appropriate step to take following the passing of Her Majesty Queen Elizabeth II.
"We will work with our clubs and members in the meantime to ensure appropriate steps are taken throughout the period of mourning."
The Scottish Youth FA stated last night that it was "awaiting further guidance" and would provide an update today on children's and youth football fixtures this weekend.
Discussions are also said to be taking place with UEFA over next week's European games involving Scottish clubs. Celtic and Hearts are due to travel to away matches in Poland and Latvia respectively, with reports suggesting that these fixtures will still go ahead. But European games due to take place in the UK could still be postponed, including Rangers' Champions League clash with Napoli scheduled for Tuesday.
The Scottish Premiership fixtures scheduled for next weekend, September 17 and 18, include Hibs v Aberdeen on Saturday and Motherwell v Hearts on Sunday. The Scottish Cup first round is also scheduled for next weekend.
The British Horseracing Authority has announced that racing will resume on Sunday, but the fixtures scheduled for Musselburgh racecourse this weekend have been cancelled as a mark of respect because as the Queen's body lies in rest in St Giles' Cathedral in Edinburgh.
Bill Farnsworth, general manager of Musselburgh Racecourse, said: "While protocols permit racing to resume on Sunday it would be inappropriate for us to stage our meeting as the Queen's body rests in nearby St Giles' Cathedral and as a mark of respect the decision was taken to abandon."
The plan for what happens next when the Queen dies, called 'Operation Unicorn' when she passes in Scotland, is set out for nine days following the monarch's death and includes the option to postpone sports fixtures.
Sports event organisers were told this morning that they were under no obligation to do so. Official guidance does, however, does recommend that sports bodies consider cancelling events on the day of the state funeral, likely to be a week on Monday.
Scottish Rugby last night announced the "suspension of all domestic competitive matches" this weekend. That includes Scotland women's Test match against Spain at DAM Health Stadium in the Capital on Sunday. A decision on Edinburgh Rugby's away match against Treviso in Italy tonight is expected soon.
All of today's race meetings in Britain have also been cancelled, while the second day of golf's PGA Championship at Wentworth will not take place and there will be no play in cricket's Test match between England and South Africa. Cycling's Tour of Britain has cancelled its final three stages in Gloucestershire, Dorset and the Isle of Wight.
News of the Queen's passing broke during the half-time interval of Hearts' Europa Conference League match against Istanbul Basaksehir at Tynecastle, with the players wearing black armbands and resuming to a minute's silence, which was interrupted by a minority of fans and had to be cut short.
The Queen was a Patron of the Scottish FA, and president Rod Petrie joined the tributes.
"On behalf of the Scottish football family, I send my condolences to the Royal Family following the death of Her Majesty Queen Elizabeth II," said Petrie the former Hibs chairman.
"We will join the nation in a period of mourning and reflect on the indomitable spirit that characterised Her Majesty's long reign and the enduring legacy she leaves behind."
"Her Majesty's love and affinity for Scotland is well-known and long-established and we at the Scottish FA are deeply saddened by the passing of our Patron."
Murdoch MacLennan, chairman of the SPFL, said: "The death of Her Majesty Queen Elizabeth II marks the end of a glorious, momentous reign.
"Our thoughts, prayers and sincere condolences go out to the Royal Family as we give thanks for the selfless contribution of our country's longest-serving monarch."
Hibs, Hearts and other football and sports clubs across Edinburgh and the Lothians have being paying tribute to the Queen on social media.
