Ex-international Darren Cave has said his generation “couldn’t stomach” it if Brexit interrupted the “unique balance that represents Irish rugby so successful”.
In a impartial row for the Sports Chronicle, the Ulster centre said the Brexit deadlock was a “threat” to the Good Friday peace deal.
“Being a proud Ulsterman and playing for Ireland should not be complicated in the 21 st Century, ” he added.
Cave also expressed mortification at the “very sad state of affairs” at Stormont.
Cave, from Holywood in County Down, has been covered 11 hours by Ireland, constituting his last-place international look in 2015.
