The English Football League has removed the need for clubs to test players for Covid-19 on matchdays in an effort to prevent late postponements.
Hull City's Championship game with Blackburn on Boxing Day was called off about two hours before kick-off when away fans were already travelling.
The EFL accept the situation was not ideal and believe that testing every day, apart from matchday, is enough.
The decision comes as 10 EFL games over new year have been postponed.
The New Year's Day game between Sheffield United and Middlesbrough in the Championship is the latest to be called off, following the earlier postponement of Coventry against Luton and the meeting of Swansea City and Fulham on Monday, 3 January.
