Republic of Ireland midfielder Alan Browne has tested positive for Covid-19, the FAI announced in a statement this morning.
The Preston North End player featured in Ireland's 3-0 loss to England at Wembley last night.
The FAI confirmed that there were no close contacts of the player and the rest of the squad tested negative ahead of the Republic of Ireland's game against Wales in Cardiff on Sunday.
Browne has been isolated from the rest of the group as per Covid-19 protocols, and both the HSE and UEFA have been informed.
Browne is the fourth member of the senior squad to test positive since the beginning of October, with Derrick Williams and Jack Byrne ruled out last month, while striker Callum Robinson's test returned a positive result on Tuesday.
Stephen Kenny's side has been heavily afflicted with Covid-19 related issues in the past two international windows.
Browne had been one of four players – alongside John Egan, Callum Robinson and Callum O'Dowda – ruled out of October's Nations League games against Wales and Finland through their close contact with Williams.
Three days earlier, strikers Aaron Connolly and Adam Idah were excluded from the critical Euro 2020 play-off against Slovakia as they were deemed close contacts with an FAI official who returned a positive test – which later transpired to be a false positive.
