The Premier League and other sports competitions will pay their respects to the Duke of Edinburgh this weekend following his death at the age of 99.
Buckingham Palace announced on Friday that Prince Philip had died.
Tributes to his lifetime of service poured in from the world of sport, and sportsmen and women up and down the country will observe silences and wear black armbands as a mark of respect.
Flags at Wembley and St George’s Park will fly at half-mast, the Football Association announced.
A two-minute silence was observed before the afternoon session at Friday’s cricket County Championship matches.
Players and other staff wore black armbands and flags at grounds were lowered to half-mast.
England and Wales Cricket Board chair Ian Watmore said: “I’m sure I speak for the entire cricket family when I say how sad I am to hear of the passing of the Duke of Edinburgh.
“His passion for the game we all love was well known and the trophies presented to the men’s and women’s county champions are a tribute to his dedication to our sport.
“We owe him a great debt for his support and passion over many decades.”
The Rugby Football League, the Rugby Football Union and the Welsh Rugby Union also paid tribute to Prince Philip’s lifetime of service and expressed their condolences to Her Majesty The Queen and her family.
RFL chair Simon Johnson said: “As a sport, we will stand in tribute and reflection at our Challenge Cup matches this weekend to mark the life of The Duke of Edinburgh, whose life was a model of dedication to public service.”
Tottenham manager Jose Mourinho said: “I would like to express my condolences to the Royal family and to be very honest and say I have the utmost respect for the Royal family.
“I believe that it is not just this country that is going to be sharing these feelings, because I’m not English and I know that many like myself, we have the utmost respect.”
Aintree will hold a two-minute silence before the start of racing on day two of the Grand National meeting.
The Duke was an honorary member of the Jockey Club and while never an owner in racing himself, he was a regular companion of the Queen at Royal Ascot.
In his role as a commentator for ITV Racing, 20-time champion jockey Sir Anthony McCoy paid his tribute.
McCoy said: “I was very lucky to spend time in Prince Philip’s company at Windsor Castle. He was a very interesting man and a really good polo player in his younger days.
“He was really keen on carriage driving and really good at it as well.
“A moment that really stands out for me was when he presented Her Majesty the Queen with the Queen’s Vase when (her horse) Estimate won in 2012.
“I can remember thinking that was a special moment, probably for Her Majesty, but also for horse racing as well.”
