Stephen Kenny has replaced Mick McCarthy as Republic of Ireland manager with immediate effect.
Kenny was due to step up from his role with the Under-21s in August but the decision was made to promote the former Dundalk boss following UEFA's announcement that the Euro 2020 qualifying play-offs would again be delayed by the coronavirus pandemic.
The Republic are due to face Slovakia away in qualifying play-offs, with the winner to face either Northern Ireland or Bosnia and Herzegovina.
McCarthy's contract was due to run until July 31, after the Euro 2020 finalswere originally due to finish.
Interim FAI chief executive Gary Owens said: "This has been a difficultsituation for the Association - and for Mick and Stephen in particular - in thewake of the Covid-19 pandemic and the effect it has had on the footballcalendar.
"On behalf of president Gerry McAnaney, the board of the FAI and myself, Iwant to thank both men for their professionalism and their understanding intheir dealings with the Association in these unprecedented circumstances.
"On behalf of the FAI, I wish to express our gratitude to Mick for his serviceand commitment to our national team throughout his career and particularly in his second spell as Ireland manager.
The match against Slovakia was originally due to take place on March 26, then shifted to the June international window due to the suspension of football across Europe.
UEFA announced earlier this week that no international football would go ahead in June, with no new dates announced.
