Football pays respect to Queen’s ‘indelible legacy’
The Football Association said fixtures between 9 and 11 September were postponed, adding that as a “long-standing patron” of the FA the Queen “has left a lasting and indelible legacy on our national game”.
The Premier League and EFL have confirmed that all fixtures will be rescheduled.
The Premier League took the decision to honour the Queen’s “extraordinary life and contribution to the nation” and said updates on future fixtures during the period of mourning “will be provided in due course”.
The league’s chief executive Richard Masters said: “We and our clubs would like to pay tribute to Her Majesty’s long and unwavering service to our country.
“This is a tremendously sad time for not just the nation but also for the millions of people around the world who admired her, and we join together with all those in mourning her passing.”
In Scotland, the postponements include the Scottish Professional Football League, Scottish Women’s Premier League, and Scottish Highland and Lowland Football Leagues as well as Women’s Scottish Cup fixtures.
SPFL chief executive Neil Doncaster said it was appropriate to “mark the event with all possible solemnity” and added that there would be a further update “when we have clarity over official arrangements for Her Majesty’s funeral”.
