Teenage pair Caoimhin Kelleher and Michael Obafemi have kept their places in the Republic of Ireland squad to face Northern Ireland and Denmark in the next seven days.
Liverpool goalkeeper Kelleher (19) and Southampton striker Obafemi (18) have been fast-tracked into Martin O'Neill's plans, with an ankle injury to Obafemi's club-mate Shane Long increasing the prospect of a first cap for the Dublin-born forward.
Obafemi is eligible to represent Ireland, England (residency) and Nigeria (ancestry) leading to some concern that a repeat of the Declan Rice dilemma could reocccur.
Southampton manager Mark Hughes said last week that he was "not sure whether or not he’s made a definitive decision in terms of where he feels his international future lies" but an appearance against the Danes in the Nations League would tie the young striker to Ireland.
Blackburn's Derrick Williams misses out with a hamstring problem while Newcastle defender Ciaran Clark is the most high-profile absentee from the initial extended panel named last week.
Clark came on as a late substitute in Newcastle's 2-1 win over Bournemouth on Saturday.
Sean McDermott, Greg Cunningham, Jimmy Dunne, Richie Towell and Ryan Manning have also been cut.
Aston Villa midfielder Glenn Whelan will lead the team out as captain against Northern Ireland for his 85th senior cap on Thursday but will not travel with the squad to Aarhus for the Denmark game next Monday.
It is expected to be Whelan's final appearance in the green jersey.
