The Republic of Ireland are to play Latvia in a friendly at the Aviva Stadium on 15 November.
The FAI have confirmed the fixture, which will be the last home game of the year, and takes place four days before the friendly against Poland in Poznan.
It is not clear who will be in charge for the two friendlies, with the FAI still on the lookout for a new manager.
Under-21 boss Noel King took charge of the final two World Cup qualifying matches of the campaign.
The FAI have yet to announce whether a successor to Giovanni Trapattoni will be in place prior to the games or if King, who presided over the qualifiers against Germany and Kazakhstan, will again be in charge.
Former Republic of Ireland midfielder Ray Houghton and the FAI's high performance director Ruud Dockter are set to present their assessments over the appointment of a new manager to the FAI next week.
Martin O'Neill and Mick McCarthy are understood to be among the frontrunners for the post.
