The fixture list in England is “overcrowded and untenable”, according to the Football Association.
Hull City host Arsenal in an FA Cup fifth-round replay (19:00 GMT) on 8 March – a Champions League night.
The FA said “exhaustive discussions” had taken place with Uefa before confirming the date as it clashes with Europe’s premier club competition.
In a statement, it added: “The FA recognises that this is not an ideal solution for everyone.”
Premier League side Arsenal were held to a goalless draw at home by Championship leaders Hull on 20 February.
On the same date as the replay, Real Madrid play Roma and Wolfsburg meet Gent in the second legs of their Champions League last-16 ties.
The FA said: “It does strengthen the case for footballing bodies to work closely together in a positive, collaborative way to resolve the overcrowded and untenable fixture schedule.”
It was revealed last week that FA Cup replays could be scrapped in order to trim the fixture list.
The FA also has concerns the season leaves the national team tired for major summer tournaments.
