The FAI has confirmed one Republic of Ireland player has tested positive for coronavirus, just two days before a friendly match against England at Wembley.
In a brief statement, the association said the player is self-isolating and that Uefa and the HSE had been notified.
All of the other squad members and association staff have tested negative.
The player, who is asymptomatic, is likely to be tested again before any final call is made on his availability.
A positive result on a member of staff last month led to the exclusion of young strikers Aaron Connolly and Adam Idah, both of whom were regarded as “close contacts”.
The result was subsequently deemed to be a false positive.
