Darlington say the club are currently awaiting league advice over their next two fixtures.
Darlo have had one of their players test positive for COVID-19 this week, which saw the postponement of their match with Gateshead.
With the squad now in self-isolation, the National League North club have said:
“We await league advice on Saturday’s home game against Hereford and the away game at Leamington on Tuesday 8th December.
“We would like to wish the player concerned a speedy recovery, and also thank our opponents and the league for their co-operation and understanding.”
