After not being selected by the Kiwis for the World Cup, Warriors hooker Issac Luke attempted to switch allegiances and play for Ireland.
Ahead of selecting his squad, Irish coach Mark Ashton noted Luke wanted to play for Ireland which he qualifies through his grandparents.
"We got a list from the NRL telling us who qualifies and Issac Luke, who qualifies through his grandparents, put his hands up," Aston said.
"We're a bit gutted because he didn't get the paperwork in on time.
"I think he thought he'd probably play for New Zealand and by the time he came back to us the chance has gone.
"But he wants to play for Ireland one day."
Roosters playmaker Luke Keary was also eligible to play for Ireland but chose to undergo hip surgery.
"Luke Keary would have also been massive for us. He 100 per cent wants to play and we were excited to have him but he had to pull out to have hip surgery," Ashton said.
