The semi-finals of the FA Cup will be played at Wembley on the weekend of April 22 and 23.
That means Brighton vs Man City – a Premier League clash that was due to take place on the Sunday – will be postponed.
Fulham are due to play Leeds at 12.30pm on April 23 with Man United facing Chelsea at 5.30pm the same day.
Whoever wins in the match between United and Fulham this evening, their game will also need to be postponed and rearranged.
