Republic of Ireland player Alan Browne has tested positive for Covid-19.
The Preston midfielder played the full 90 minutes for the Boys in Green in their 3-0 defeat to England on Thursday night and will now miss the UEFA Nations League games with Wales and Bulgaria.
The FAI said in a statement: "The Football Association of Ireland can confirm Ireland midfielder Alan Browne has tested positive for COVID-19.
"The player has been isolated from the group as per COVID-19 protocols, and the HSE and UEFA have been informed of this development.
"There are no close contacts of the player and the rest of the staff & squad tested negative ahead of Sunday's UEFA Nations League fixture against Wales in Cardiff."
It is the latest blow for manager Stephen Kenny after Callum Robinson tested positive for the virus earlier this week.
Brighton's Aaron Connolly was also ruled out of this month's internationals after suffering an injury earlier in the week, while James McCarthy and Seamus Coleman were late injury blows ahead of last night's game.
Conor Coady was forced to withdraw from the England squad for the game last night and isolate despite two negative COVID-19 tests.
He was identified as a close contact to someone who has tested positive for coronavirus via track and trace.
