All English and Northern Irish football and all professional Scottish football has been postponed this weekend as a mark of respect following the death of Queen Elizabeth II.
Ten Premier League and six Scottish Premiership fixtures were scheduled.
EFL games were due to take place on Friday and Saturday, with six Women's Super League fixtures - the first of the season - on Saturday and Sunday.
England's National League, FA Trophy and grassroots football is also off.
Friday's play at golf's PGA Championship was called off, along with all British horse racing and cricket's Test between England and South Africa.
British horse racing will remain off on Saturday and return on Sunday, reports BBC.
British Boxing Board of Control tournaments have been postponed on Friday, with a decision yet to be made on the world boxing title fight between Savannah Marshall and Claressa Shields.
Sunday's Great North Run will go ahead as planned, with organisers saying it is "an opportunity to come together and express our condolences while celebrating the life of our extraordinary Queen" and that the event would be "more subdued out of respect".
Queen Elizabeth II, the UK's longest-serving monarch, died on Thursday aged 96, after reigning for 70 years.
The government's national mourning guidance advised that cancelling fixtures was not obligatory, leaving the decision up to individual sports.
Government guidance for the day of the funeral also advised that cancellation was not obligatory, but suggested events could be rescheduled so that they do not clash with the timings of the service.
