The Republic of Ireland will be without a number of players when they set off for New York on Wednesday ahead of their matches against Costa Rica and Portugal.
Jon Walters and Ciaran Clark are battling illness and injury respectively, while it has been confirmed by the FAI that John O'Shea, Seamus Coleman and Damien Delaney will not make the trip following talks with manager Martin O'Neill.
"Ciaran Clark is suffering from a minor knee injury following warm up before the Italy match and remains in England to receive treatment from his club," said an FAI statement.
"Jon Walters was excused from training today as he is suffering from a stomach bug and may report tomorrow if symptoms improve.
"John O'Shea, Seamus Coleman and Damien Delaney have spoken to the manager and it has been agreed that they will not travel with the squad to New York tomorrow."
Full-back Stephen Ward will not travel for the Costa Rica game but may link up for the Portugal tie on 10 June.
Wes Hoolahan and David Meyler sat out today’s training session in Malahide, while Anthony Pilkington was limited to gym work. All three are expected to travel tomorrow.
