The Bucks, under the interim management of Dennis Greene, were due to welcome the West Yorkshire side at the New Bucks Head for a National League North clash.
But there has been positive Covid cases in the Lions camp, which means the visitors will not make the trip.
The postponement was confirmed at 10.30am on Tuesday, with supporters who have purchased tickets offered refunds.
A new date for the re-arranged fixture will be confirmed in due course.
Telford, who are still searching for a new first-team boss, are scheduled to host Curzon Ashton on Saturday.
However, that fixture is also up in the air after the Manchester side were struck by coronavirus issues of their own.
The Nash, whose manager Steve Cunningham was recently axed following talks to become the new Bucks boss, were due to host Gateshead tonight but that clash has been postponed due to positive cases in the home squad.
It places Curzon's visit to Shropshire this weekend in doubt.
Meanwhile, Telford have extended the loan of young Salford left-back Kevin Berkoe, 20, for another month.
The 20-year-old has made six appearances for the Bucks.
