Northern Ireland manager Lawrie Sanchez has named three new faces in his 19-man squad to face Portugal in a friendly at Windsor Park on Tuesday.
Dean Shiels (Hibernian), Brian McLean (Motherwell) and Peter Thompson (Linfield), all aged 20, make the step up.
Shiels and Glasgow-born McLean, who is on loan from Rangers, have both played for the North's under-21 side.
Thompson, whose day job is as a postman, gets his reward for scoring 18 goals this season for his Belfast-based club.
Sanchez turned to the young trio as a number of key players are unavailable to face the visitors through injury.
Record scorer David Healy, goalkeeper Roy Carroll, captain Aaron Hughes, Damien Johnson and Chris Baird are all ruled out.
Northern Ireland squad: Taylor (Birmingham), Ingham (Wrexham), Murdock (Rotherham), Craigan (Motherwell), Capaldi (Plymouth), Duff (Burnley), McAuley (Lincoln), McLean (Motherwell), Davis (Aston Villa), Brunt (Sheff Wed), Elliott (Hull), McCann (Cheltenham), Gillespie (Sheff Utd), Quinn (Peterborough), Feeney (Luton), Jones (Crewe), Sproule (Hibs), Thompson (Linfield), Shiels (Hibs).
