Five players have withdrawn from the Republic of Ireland squad for next week's games against Ecuador and Bolivia in the United States.
Stephen Ireland is ruled out because of family commitments
Family commitments rule out Sunderland pair Liam Miller and Stephen Elliot plus Manchester City's Stephen Ireland.
Sheffield United's Derek Geary has ankle and thigh injuries while Wigan's Caleb Folan has a hamstring tear.
Cork City's Joe Gamble and Aston Villa's Stephen O'Halloran were drafted into the squad on Tuesday.
Republic of Ireland manager Steve Staunton said that he won't decide on whether to add more players to the squad until he sees the outcome of Wednesday night's Championship play-off between West Brom and Wolves.
West Brom's Paul McShane and the Wolves duo Darren Potter and Andy Keogh were included in an inexperienced squad last week.
Uncapped Gamble was called into the squad for last year's friendly against Chile but O'Halloran is receiving his first senior call-up.
O'Halloran has represented the Republic at all underage levels while Gamble has a B international cap.
The Republic face Ecuador in New York on 23 May and Bolivia in Boston three days later.
