Uncapped Tottenham teenager Troy Parrott has remained in the Republic of Ireland squad for the vital home Euro 2020 qualifier against Denmark.
The 17-year-old, who has played only one competitive game for Tottenham, was named in an extended squad last week.
Manager Mick McCarthy says Parrott will earn his debut in the friendly against New Zealand on 14 November - four days before the Denmark game.
"He will feature against New Zealand," McCarthy told the FAI website.
"All he has to do is look at how well Aaron Connolly did last time in Georgia and Switzerland to see the opportunity that is there for him now.
"The same will apply for other players who will get a chance against New Zealand and can give me something to think about for the Denmark match."
Southampton's Long omitted from final squad
Sheffield United striker David McGoldrick, who missed the qualifiers against Georgia and Switzerland because of injury, returns to the squad as do fit-again pair Robbie Brady and Ciaran Clark but Southampton's Shane Long is among five forwards who drop out after being named in the original 39-man squad.
Long did not feature in the September and October squads after falling out of favour at Southampton.
Crystal Palace midfielder James McCarthy, who hasn't played for the Republic since a World Cup qualifier win in Moldova in October 2016, is also missing after opting out for personal reasons.
In September, McCarthy withdrew from the squad for the Euro 2020 qualifier against Switzerland as the Republic boss agreed to let him focus on duty for his new club following his return to action after a long period out.
Brady missed all of the Republic's recent games because of a rib injury while McCarthy watched central defender Clark score for Newcastle United at the weekend.
Injury doubts Darren Randolph, Glenn Whelan and Matt Doherty are all included with McCarthy optimistic all three will be fit for the crunch Denmark game.
Whelan and Doherty both had to be substituted because of injury during their clubs' games at the weekend while keeper Randolph has missed Middlesbrough's last three matches because of a thigh injury.
Win over Danes should clinch Euro 2020 spot
Like Parrott, Celtic defender Lee O'Connor has been promoted from the Under-21 squad and is also likely to earn a first cap against New Zealand.
Keepers Caoimhin Kelleher and Keiren Westwood drop out of the extended squad as do defenders Cyrus Christie, Darragh Lenihan, Ryan Manning and Nathan Collins.
Shamrock Rovers midfielder Jack Byrne retains his place in the squad as strikers Aiden O'Brien, Ronan Curtis, Michael Obafemi and Kieran Sadlier fail to survive the cut from the original squad.
A Republic win on 18 November should be enough to secure them a spot at Euro 2020 although McCarthy's side will need a 2-0 victory to qualify if Switzerland pick up only four points from their final two games against Georgia and Gibraltar.
If that route fails, they may still have the fallback option of a play-off place.
