The EFL has postponed Friday night's fixtures as a mark of respect following the passing of Queen Elizabeth II.
Burnley were due to take on Norwich City in the Championship while Tranmere Rovers were set to play host to Stockport County in League Two, but both games will now be rescheduled.
A statement from the EFL read: "As a mark of respect, following the passing of Her Majesty, The Queen Elizabeth II earlier today, the EFL has confirmed that its fixtures scheduled for tomorrow evening (Friday 9 September) – Burnley v Norwich City and Tranmere Rovers v Stockport County - have been postponed.
"A determination regarding the remainder of this weekend's scheduled fixtures will be made following a review of the official mourning guidance, in addition to further consultation with DCMS and other sports on Friday morning."
A decision has not yet been made on whether matches will be played this weekend but the full fixture list in the UK is expected to be postponed.
An announcement is likely to be made on Friday morning, with Premier League games also being temporarily cancelled and rescheduled.
