Reading and Coventry City may rearrange their schedule match in December, with England potentially playing on the same day.
The Championship is currently on a month-long break due the beginning of the World Cup, which gets underway on Sunday.
The break covers the group stage and the last 16 fixtures of the winter competition, with teams returning the same weekend as the last eight.
Due to return on Saturday, December 10, with a home match with the Sky Blues- the Three Lions could play their quarter-final on the same day, if they were to reach that stage.
The EFL have given clubs permission to rearrange their fixture on that day, as long as both teams agree to the new time.
World Cup fixtures are due to take place at 2pm and 7pm on the same day, making it almost impossible for travelling fans to watch the ties.
Reading could be without Junior Hoilett, Mamadou Loum and Baba Rahman- if their respective nations progress far in the tournament.
Hosts Qatar kick-off the football festival against Ecuador, while England open their account on Monday against Iran.
