Republic of Ireland midfielder Alan Browne has tested positive for coronavirus after playing the full 90 minutes against England on Thursday.
Browne was part of the Ireland team beaten 3-0 at Wembley after goals from Harry Maguire, Jadon Sancho and Dominic Calvert-Lewin.
Testing since that match has revealed the Preston North End man has contracted COVID-19, however.
Browne, who contested a game-high 13 duels, has had “no close contacts”, FA Ireland reported on Friday.
“The rest of the staff and squad tested negative ahead of Sunday’s UEFA Nations League [game] against Wales in Cardiff,” a short statement read on Twitter.
While Ireland visit Wales then host Bulgaria in the Nations League, England go to Belgium before playing Iceland at Wembley.
The Iceland fixture had been in some doubt due to the visitors’ prior match in Denmark, where a latest coronavirus outbreak has led to tightening of travel restrictions.
But Iceland were granted exemption on Thursday, allowing the game to go ahead.
