Declan Rice is "still deliberating" over his international future and has not been named in Martin O’Neill’s squad for the upcoming UEFA Nations League game against Wales and the friendly with Poland.
The West Ham man was a glaring omission from the panel and O’Neill said his international future is still not clear.
Although the 19 year old has played three times for Ireland, all of those appearances have come in friendlies, meaning he can still switch to England, the country of his birth.
"I’ve spoken to him, I’ve spoke to the family," said the manager. "His father is an absolute gentleman, he’s very keen for him to play for us too but the lad just needs a little bit more time.
"He’s been brilliant for us in senior games. I think the Republic of Ireland have done everything to sell the country to him. He’s been welcomed by the players, by the fans too.
"I’m not so sure what else we can do. Obviously the country of his birth have come calling."
Back in March, ahead of the Turkey friendly, Rice told RTÉ Sport there was "no decision to be made" regarding his international future.
"I’m here with Ireland and I’ve been called up by Martin. I’m really looking forward to this week and I’m looking forward to getting to know the boys better.
"I haven’t had a call from anyone at the FA. Not at all. England have never wanted me at underage level, it’s always been Ireland."
Preston North End striker Callum Robinson has been named in the panel.
Robinson aired his desire to play for Ireland back in March.
The Northampton-born 23-year-old Robinson qualifies for Ireland through his maternal grandmother, a Monaghan woman.
With the paperwork cleared, Robinson will head for international duty with Lilywhites club-mates Graham Burke and Alan Browne. Sean Maguire remains unavailable through injury.
Another fresh face is goalkeeper Sean McDermott, who plies his trade for Kristiansund in Norway, the country of his birth. McDermott’s father hails from Donegal.
