Sporting bodies are in discussions regarding plans for next Saturday's fixtures, as Prince Philip's funeral will take place at Windsor Castle that afternoon.
A national minute's silence will be observed as the ceremonial royal funeral begins at 3pm.
The funeral will take place on a busy sporting weekend with the FA Cup semi-finals, a full Football League programme, the Women's Six Nations and the opening day of the World Snooker Championship among the events on the calendar.
The Football League has announced that matches scheduled to begin at 3pm will be rearranged.
This will include Wycombe Wanderers' fixture away at Swansea City at the Liberty Stadium, which is due to kick-off on the same day at the same time.
An EFL spokesperson said: "As a mark of respect, EFL matches scheduled for 3pm on Saturday, April 17 will be moved to avoid a clash with the funeral of HRH The Prince Philip, Duke of Edinburgh.
"The EFL will now work with its clubs to determine at what time the matches will be played, giving consideration to the timing of the service.

In the Premier League, Wolves are due to host Sheffield United at 3pm, following the lunchtime fixture between Newcastle and West Ham.

The Government's published advice regarding the period of national mourning states: "The decision as to whether sporting fixtures continue to go ahead is at the discretion of organisers.
"Organisers may wish to consider using black armbands and observing a silence before matches are played."
