Alex Pearce and Robbie Brady have been added to the Republic of Ireland squad to play Oman on Tuesday after five players were allowed return to their clubs.
Robbie Keane, Darren O'Dea, John O'Shea, Jon Walters, Glenn Whelan have departed the squad following last night's World Cup qualifying victory against Kazakhstan.
Manchester United winger Brady is promoted from the Under-21 team as record scorer at that level, while Pearce was recently contacted by Giovanni Trapattoni's representatives with a view to representing the nation of his grandmother's birth.
He previously won two Scotland Under-21 caps.
"It would be a dream come true to pull on the Irish jersey. It's something that I've been dreaming about for a while now," Pearce told his club Reading’s website earlier this week.
"My dad is proud to be Irish, my grandmother was born in Dublin and that pride has been passed on to me.
"I represented Ireland at under-14 level a while ago, which a lot of people don't know -- so I have an affiliation with the country there too.
"In the Premier League you get much more media coverage, you're out in the spotlight more, so if I can stay in the team and do well hopefully the call will come.
"I'm dying for an opportunity to get that first call up and show Mr Trapattoni what I can do."
