Dundee United's Paul Paton joins Milton Keynes Dons midfielder Ben Reeves as the new faces in the Northern Ireland squad for Wednesday's game against Cyprus in Nicosia.
Kilmarnock midfielder Sammy Clingan has withdrawn from the squad with a knee injury but the integration of Paton and Reeves into the panel gives boss Michael O'Neill more options.
Clingan was forced off in the first half of Kilmarnock's defeat by St Mirren on Saturday but the international door has opened for Paton whose father was born in Larne.
The 26-year-old midfielder previously played for Queen's Park and Partick Thistle before signing for the Pars last summer.
Wednesday's game will go ahead despite security concerns sparked by the bombing of a referee's car on the island.
All first division matches in Cyprus were cancelled at the weekend but the international friendly will proceed.
O'Neill will use this match as preparation for the Euro 2016 qualifiers, which begin with a trip to face Hungary on September 7.
Northern Ireland also face Uruguay in Montevideo on May 30 and Chile in Valparaiso on June 4 in friendlies.
