Michael McArdle has adjusted his selection list for the upcoming international fixtures.
The Northern Ireland women's team will face Portugal in a two-match tie scheduled for late October.
One game is set to take place at Larne's Inver Park on 9 October, with the second leg occurring in Portimao on 13 October.
McArdle has brought five fresh faces into the twenty-three-man roster for these crucial World Cup 2027 qualifying encounters.
Kess Elmore and Lucy-Jayne Grant are among the newcomers making their debut for the Republic of Ireland's national side.
Elmore, who is twenty-seven years old, plays as a forward for Sparta Prague in the Czech Women's First League.
Her club career includes stints with St Polten in Austria, Brooklyn in the United States, and AS Saint-Etienne in France.
The Liverpool-born player has featured in multiple UEFA Women's Champions League and Europa Cup competitions during her professional tenure.
Grant previously spent time at Liverpool Women's academy before moving through the US college system with UConn Huskies and Oregon Ducks.
Elmore qualifies for the Republic of Ireland through her father, who was born in Lisburn.
