Republic of Ireland under-21 manager Stephen Kenny has remained in a hospital in Sweden after becoming unwell following the squad's match on Tuesday.
The team was in Kalmar this week for their European Championship qualifier against Sweden, which they won 3-1.
The FAI today said Mr Kenny became unwell as the squad made their way home yesterday.
The statement explains: "Stephen was examined by the FAI’s medical staff and decided to stay behind for treatment at a local hospital.
"Stephen expects to be discharged in the coming days and is looking forward to beginning preparations ahead of the two European Under-21 Championship qualifiers next month."
The 47-year-old become the U21 coach last year.
He's set to take over from Mick McCarthy as the senior team manager next year after the current coach leaves the job after the Euro 2020 championship.
