The Premier League faces a logistical nightmare to squeeze the postponed Manchester United versus Liverpool into the schedule during the final weeks of the season.
Sunday's match at Old Trafford became the first Premier League fixture to be called off because of fan protests after United supporters angry at the club's American owners stormed the pitch and clashed with police.
With protests also taking place outside the Lowry Hotel, where the United players and staff were staying, the decision was taken to postpone.

However, finding a new date for the fixture will prove challenging with Premier League planners set to discuss the situation with representatives from the clubs, the police and the local safety advisory group.
The Premier League declined to comment on when the game would be rearranged for when contacted by Sportsmail.
The game can't be played this week because United play the second leg of their UEFA Europa League semi-final against Roma in Italy on Thursday evening. Accordingly, they will be flying out on Wednesday.
Both teams are in action at the weekend, with Liverpool hosting Southampton on Saturday evening and United travelling to Aston Villa on Sunday afternoon.

Bottles and other projectiles were hurled at the riot officers from the protesting fans
Liverpool are not in action during the following midweek but United have a home game against Leicester City scheduled for 6pm on Wednesday May 12.
It's then United who have a blank weekend but Liverpool travel to West Bromwich Albion on Sunday May 16.
United's game against Leicester cannot be moved to that weekend in order to free up a midweek slot because the Foxes are playing Chelsea in the FA Cup final on Saturday May 15.
One solution could be to move Liverpool's trip to West Brom to the previous midweek and rearrange the fixture for either May 15 or 16.
The following midweek sees both teams in action in what is the penultimate set of Premier League games.
Thursday May 6 Roma (A)
UEFA Europa League semi-final, second leg
Sunday May 9 Aston Villa (A)
Wednesday May 12 Leicester City (H)
May 19 TBC Fulham (H)
Sunday May 23 Wolves (A)
Wednesday May 26 Possible UEFA Europa League final
