The Premier League, EFL, Premiership Rugby, F1 and British Horseracing have adjusted their schedules "as a mark of respect" to avoid clashing with Saturday's funeral of Prince Philip.
The Duke of Edinburgh died at the age of 99 on Friday and his funeral will be held at St George's Chapel, Windsor, at 15:00 BST on Saturday, 17 April.
A national minute's silence will be held at 15:00.
The Football Association recommends no games played between 14:45 and 16:15.
In addition, a minute's silence should be observed before matches and black armbands worn.
All flags at Wembley Stadium and St George's Park will also fly at half-mast.
A statement said: "The FA's thoughts continue to be with Her Majesty the Queen, our president, HRH the Duke of Cambridge, and the wider royal family during this difficult time."
In the Premier League, Wolverhampton Wanderers' home game against Sheffield United, which had been scheduled to kick off at 15:00, will be moved to 20:15.

Formula 1 has changed the schedule of this weekend's Emilia Romagna Grand Prix to ensure cars are not on track at the same time as the Duke of Edinburgh's funeral.
Saturday's on-track sessions have been moved forward an hour, with qualifying now starting at 14:00 local time (13:00 BST) and final practice at 10:00 BST.
Friday practice has also been moved as a result, to comply with regulations demanding specific gaps between sessions. The first hour-long session will be at 10:00 BST and the second at 13:30.
In racing, the Scottish Grand National at Ayr has been switched from 17 to 18 April.
