The Premier League are waiting for the outcomes of Chelsea and Manchester United's European quarter-finals before settling on a date for their rearranged domestic fixture.
United's visit of Chelsea was originally scheduled for the weekend of April 22 but that has been postponed as United reached the FA Cup semi-finals and will play Brighton at Wembley on April 23.
Chelsea face Real Madrid in the Champions League quarter-finals on April 12 and 18 while United take on Sevilla in the last eight of the Europa League over the next 10 days.
