Horse racing was halted on Thursday following the death of Her Majesty Queen Elizabeth II, while Friday’s play in cricket’s Test match between England and South Africa was called off.
All Friday’s race meetings in Britain have also been cancelled, along with the same day’s Rachael Heyhoe Flint Trophy cricket fixtures.
The second day of the PGA Championship golf on Friday will not take place.
The English Football League has also postponed its two games on Friday.
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.
It is scheduled to be the opening weekend of the Women’s Super League and the Premiership Rugby season, while the Great North Run is due to take place on Sunday.
The Irish FA has announced that all football in Northern Ireland scheduled for this weekend will not take place.
The government’s national mourning guidance states cancelling or postponing sports fixtures is not obligatory and “at the discretion of individual organisations”, including on the day of the state funeral.
On the day of the funeral, the guidance suggests events could be rescheduled so that they do not clash with the timings of the service and that organisers could hold a period of silence or play the National Anthem at events, with players wearing black armbands.
Queen Elizabeth II, the UK’s longest-serving monarch, died aged 96, after reigning for 70 years.
