Two members of Galway United's first-team squad have tested positive for Covid-19, with their match against Drogheda United on Friday postponed by the Football Association of Ireland.
As a result of two positive cases, the entire first team squad and staff are now restricting their movements and awaiting tests, following HSE and government guidelines.
A new date for the fixture will be announced shortly.
It is the first time that cases have been reported in the league, which has been credited for its smooth running since returning to competitive games on 31 July.
Galway beat Longford Town 6-2 last Saturday as their remarkable turnaround under John Caulfield continued.
They are on the verge of entering the play-off spots with three games to go in the second tier.
The play-offs are scheduled for the first week of November.
It's just the second League of Ireland match to be postponed since the restart, with Waterford FC's game in Sligo called off due to possible cases, which subsequently proved to be negative.
