The English Football League announced the postponement of 9 September's two scheduled matches, adding "a determination regarding the remainder of this weekend's scheduled fixtures will be made following a review of the official mourning guidance."
Racing in mourning
It was reported that a meeting of governing bodies across a range of sports has been scheduled for 9 September, where officials will set out government guidance on the official 10-day period of mourning.
It is understood sports chiefs will be left to make their own judgements regarding the staging of events.
The British Horseracing Authority said the sport was in mourning for the queen, who showed an intense passion for racing throughout her life.
"Her Majesty has been one of the greatest and most influential supporters in the history of horse racing," the BHA said.
"Her passion for racing and the race horse shone brightly throughout her life."
The BHA's statement added: "It is right, therefore, that all racing is suspended for today and tomorrow as we begin to grieve Her Majesty's passing and remember her extraordinary life and contribution to our sport and our nation."
Brazilian football great Pele was among huge numbers of sports stars who paid tribute to the queen.
"I have been a great admirer of Queen Elizabeth II since the first time I saw her in person in 1968, when she came to Brazil to witness our love for football and experienced the magic of a packed Maracana," he tweeted.
"Her deeds have marked generations. This legacy will last forever."
'Grievously missed'
Former England captain and current World Rugby chairman Bill Beaumont tweeted: "Her Majesty The Queen will be remembered as a much-loved, visionary monarch, who cared deeply about all people under her reign, and was an avid supporter of sport and its power to unite communities."
World Athletics president Sebastian Coe said the queen had shown "exceptional leadership, grace, wisdom and fortitude."
