Results of their latest round of covid-19 testing will be known today.
Republic of Ireland manager Stephen Kenny has praised the professionalism of his players after a difficult three days.
His side couldn't make a breakthrough against Wales at the Aviva Stadium, drawing 0-0 in their UEFA Nations League game yesterday.
The manager saw five players ruled out of the game, after one positive Covid-19 case saw four additional members of the squad deemed close contacts.
Kenny says he couldn't ask more from his makeshift team, in spite of another scoreless result.
The results of the latest round of FAI Covid-19 screening will be known later today.
The squad are due to travel to Helsinki tomorrow, ahead of their meeting with Finland.
Adam Idah will return to the squad, having missed Thursday's draw with Slovakia in the playoffs.
He's been given the all-clear to link up again, after the Covid-19 case which ruled him out of the game in Bratislava was deemed to be a "false positive".
Dara O'Shea, Jason Knight, Ryan Manning and Ronan Curtis have also been called into the group.
Finland beat Bulgaria 2-0 last night in the other game in Ireland's group.
Those results mean that Ireland are in third position in the table on two points, five behind leaders Wales.
