Martin O'Neill will let Jeff Hendrick leave Ireland camp as Premier League clubs battle to sign the midfielder
Ireland manager Martin O'Neill will allow players leave the camp if they have the possibility of securing a transfer before the close of the window.
Hull are in talks with Derby County over a move for Jeff Hendrick which could lead to the Dubliner travelling to England to complete a medical.
However, it is understood that Burnley are also interested in signing the midfielder, who excelled for Ireland at Euro 2016.
"It's not a problem at all," he said, "If anything like that happens to any of the players. They have permission to go because they are trying to get their futures sorted out. While it might be an awkward time, it's inevitable. I really don't know (what will happen) at the moment."
Seamus Coleman and James McCarthy will miss the Oman game through injury as they seek to prove their fitness for next Monday's qualifier in Serbia. John O'Shea has arrived late with the camp and remains a doubt.
O'Neill gave the strongest hint possible that Robbie Keane will start his farewell match. Shay Given has also been invited back for a non-playing role in the occasion, with the Irish boss stating that the Donegal man did not wish to take the limelight away from the man of the moment.
