The FA Cup tie between Barrow and AFC Wimbledon has been postponed after the Dons reported a number of positive tests for Covid-19 within their squad.
Wimbledon did not disclose the number of positive results but said the first-team squad "will now all self-isolate".
"Testing of all first-team players and staff is now taking place, as well as under-18 squad members as a precautionary measure," the Sky Bet League One club said on their website.
Saturday's fixture, scheduled to be played at Barrow's Holker Street home, will now be rearranged on a date to be confirmed.
The news comes days after Wimbledon made an emotional return to Plough Lane to play at their newly-built stadium, a 2-2 draw with Doncaster on Tuesday.
They are next due to face Wigan at home next Saturday.
