Nottingham Forest have been sent official guidance by the government ahead of Monday's game against Leeds United.
The Cabinet Office have published official guidance on major events, entertainment and sports, which says there is "no obligation" to postpone fixtures during the period of National Mourning after the death of Queen Elizabeth II.
They say this is "at the discretion of individual organisations", but advise that they "might wish to consider cancelling or postponing" on the day of the State Funeral. The date of the funeral is yet to be confirmed, but is likely to take place in approximately ten days' time.
