Sheffield United's Brian Howard has conceded his dream of representing Scotland is all-but over.
The 25-year-old, who has represented England at Under-21 level, had hoped to switch allegiances as his father is Scottish.
Howard was actually called up by George Burley for Scotland's friendly against Croatia last March before Fifa stepped and objected.
The Blades midfielder had hoped to earn special dispensation to play as he was too old to inform Fifa of his decision, but now admits the regulations cannot be adapted for him to play for Scotland.
"It can't get resolved. There's a Fifa ruling which says before I turn a certain age, I think it might be 25, I have to say if I'm going to switch allegiances," Howard told the Football League podcast.
"I was two months into my 25th year when I got called up for Scotland and they said, 'No, it's too late because you've played for England Under-21s. You can't play'. We've looked in to it.
"I've had all sorts of people through media and different football lines look into it but it looks like Fifa, the governing body that's supposed to be there for footballers, does seem to be against them and won't change the rules.
"I've got a huge Scottish family so I would have loved to get the blue shirt on and played in front of the Scots.
"I still get goose pimples when I hear 'Flower of Scotland' so that would have been lovely, but at the moment it doesn't look like it's going to happen."
