The list of EFL postponements over the festive period continues to grow, with four of Wednesday's scheduled Championship games cancelled.
Sheffield United v Hull City was called off on Tuesday because the Tigers had insufficient players to play the game due to Covid-19 cases and injuries.
Birmingham v Peterborough, Reading v Fulham and Swansea v Luton had already been postponed for similar reasons.
Twelve other EFL games scheduled for Wednesday have been postponed.
West Bromwich Albion's home game with Preston on Thursday will also not go ahead because of coronavirus cases.
Birmingham, whose trip to Fulham on Sunday was postponed after too many Covid cases, say they do not have "a sufficient number of players available" to play their game on Wednesday.
