Teenage striker Rory Donnelly and Scotland-born defender James McPake have earned their first Northern Ireland call-ups for next month's friendly against Holland in Amsterdam.
Manager Michael O'Neill has named a much-changed squad for his second match in charge of the national side, with senior players including Jonny Evans, Chris Brunt, Aaron Hughes, Kyle Lafferty and Dean Shiels all excused.
That has left room for some experimentation in the 24-man party, with Swansea's Donnelly and McPake, who ended the season on loan at Hibernian from Coventry, joined by fellow uncapped duo Daniel Lafferty and Will Grigg.
There are also recalls for Crusaders defender Colin Coates, Notts County forward Jeff Hughes and Rangers striker Andrew Little.
O'Neill has also recalled former Manchester United goalkeeper Roy Carroll to the squad.
Carroll, now with Olympiakos, last played for his country in 2006 but after being sidelined by Nigel Worthington is back in the international fold.
No captain has been named for the game, with O'Neill's appointed skipper Steve Davis among the injured and other alternatives such as Hughes, Evans and West Brom's Gareth McAuley also absent.
While it is a relatively youthful squad, record goalscorer and 92-cap veteran David Healy is named, with Grant McCann and Sammy Clingan the next most experienced players with 38 and 32 caps respectively.
O'Neill has made it his mission to increase the available player pool as Northern Ireland manager and the presence of McPake, who qualifies via his grandmother, hints at a first success in that regard.
Having arrived at Hibs on a six-month loan deal he was immediately installed as club captain and led his new side to safety in the Clydesdale Bank Premier League, as well as to the Scottish Cup final.
Donnelly, meanwhile, has a chance to impress after capturing headlines in January with his move from Cliftonville to the Premier League.
Liverpool and Everton were both interested in the striker's services but it was Swans boss, and fellow Northern Irishman, Brendan Rodgers, who won the chase.
Donnelly has yet to play for first-team football for the club but has featured in the Northern Ireland Under-21 set-up.
Walsall's Grigg is also included after impressing for the Under-21s against Macedonia earlier in the month and Daniel Lafferty has been rewarded for winning a place in the Burnley side following his move from Derry City.
