Swansea City’s Championship home game with Fulham on 3 January has been postponed, taking the number of new year postponements in the EFL to eight.
It follows the loss of the Championship New Year’s Day game between Coventry City and Luton Town.
The New Year’s Day League One games at Ipswich, Plymouth and Wigan have all been postponed, as well as Sunderland v Fleetwood on 2 January.
In League Two, Salford City v Tranmere and Rochdale v Mansfield are off too.
Luton have said the number of positive cases within their squad has increased following the postponement of the game against Bristol City on 26 December.
They also had the trip to Swansea on 29 December called off.
Meanwhile, Swansea have said they have “a considerable number of positive Covid-19 cases within the playing squad”.
Lincoln chief executive Liam Scully said: “We had hoped, under new guidance, to have players returning to the squad after completing a reduced self-isolation period.
“The new rules would have allowed them to come out of self-isolation with a negative lateral flow test after seven days. Unfortunately the tests remain positive which means we cannot fulfil the fixture.
“Those who have tested positive will have completed their self-isolation periods in time for our next fixture at home to Oxford United on 8 January, which we expect to go ahead as scheduled.”
