Republic of Ireland manager Martin O'Neill has named his squad for the games against Mexico, Uruguay and Austria in June.
O'Neill unveiled a 38-man squad at the Aviva stadium, where two of the matches will be played.
The games against Mexico and Uruguay are friendlies while the match against Austria is a World Cup qualifier.
Several players were unavailable due to injury, including Seamus Coleman (leg), Ciaran Clark (knee) and David Meyler (knee).
There is a first senior call-up for Burnley defender Kevin Long, who has recently broken into the Premier League side's starting XI. The former Cork City player brings the total of SSE Airtricity League graduates in the squad to nine.
A selection of players will report for a three-day training camp in Fota Island Resort on Tuesday, May 23 - this is closed to the public and the media - before the full squad links up in Dublin on Sunday, May 28.
