An official statement released on Friday morning said it was “as a mark of respect to Her Majesty Queen Elizabeth II”.
There will be no matches in the Premier League this weekend.
The statement signed by Richard Masters, Premier League Chief Executive, said: “We and our clubs would like to pay tribute to Her Majesty’s long and unwavering service to our country.
“As our longest-serving monarch, she has been an inspiration and leaves behind an incredible legacy following a life of dedication.
“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.”
