After Manchester United and Wolverhampton Wanderers secured their progress to the last 16 of the UEFA Europa League, the two clubs' fixtures scheduled for Saturday 21 March will move to the next day.
The match between Man Utd and Sheffield United will now take place at Old Trafford on Sunday, 22 March as Ole Gunnar Solskjaer's team face LASK the Thursday before.
Likewise, Wolves' home fixture with AFC Bournemouth will now be at Molineux on Sunday, after they were drawn against Olympiacos, who advanced past Arsenal in the previous round.
The kick-off times for both matches are to be confirmed.
FA Cup doubt
However, the Old Trafford fixture is subject to both clubs' participation in the FA Cup sixth round, which also takes place that weekend.
Man Utd visit Derby County on Thursday 5 March, and Sheff Utd travel to Reading in the FA Cup fifth round the day before.
If either, or both, progress - the ties will be decided on the evening - their meeting on 22 March will be postponed.
The two teams' Premier League matches after the first legs of their round-of-16 UEFA Europa League fixtures are already scheduled for Sunday, so do not move.
