The Scottish Football Association has denied Lord Coe's claim that Britain's football associations are discussing a joint Olympic team for 2012. Coe, leader of London's bid to host the Games, raised the prospect of a Great Britain team competing at that time.
But an SFA spokesman said: "No meaningful discussions have taken place and none are planned."
The Welsh FA said that the subject had not been raised since being discussed briefly at the start of the year.
Coe had said that the football associations of England, Northern Ireland, Scotland and Wales were examining whether the idea of a 'team GB' would be feasible.
"You can't say there won't be a team to support by then," said Coe.
"The home associations are in detailed discussions now about that, specific to the 2012 games." The Home Nations need to be satisfied that there will be no pressure to participate at future World Cup and European Championship tournaments as a united side.
The four countries are individually recognised by Uefa and Fifa and they could oppose any move to amalgamate, even if it was for the 2012 Olympics.
Coe said that the organisers of London's bid to host the 2012 Games would not put any undue pressure on the associations.
"I have a personal opinion but I'm not going to wade in with my size nines and pre-judge," he said.
"Those discussions are quite properly for them, it's not for the bidding committee to determine what format it takes. But those discussions are now in place."
