Portsmouth striker Ronan Curtis has been added to the Republic of Ireland squad for Tuesday's friendly against Poland, while defender Stephen Ward is out with a foot injury.
Curtis, who has scored five goals in six games for Portsmouth this season after joining from Derry City, has impressed for Noel King's Under-21s this campaign and netted the equaliser in a 1-1 draw away to Kosovo last Friday.
However, the 22-year-old is suspended for Tuesday's qualifier against Germany in Tallaght Stadium so he will link up with the senior squad in Poland instead.
Ward, who earned his 50th senior cap in the defeat to Wales, has returned to Burnley with a foot injury.
Liverpool goalkeeper Caoimhin Kelleher has also left the squad following two days training in Dragon Park, Newport.
