Uefa has warned Spain they could be thrown out of Euro 2008, which may open the door for Northern Ireland.
Nigel Worthington's side could get a back-door pass to the finals
Uefa may step in if the Spanish government tries to interfere in the election process of the Spanish FA.
Spain topped their qualifying group for the European Championship, with NI finishing in third place.
"Uefa and Fifa deal with these sort of issues very seriously. These are no empty threats - we will back them up," said Uefa spokesman William Gaillard.
"It is similar to 1992 when Yugoslavia was suspended and Denmark, who finished second in the group, came in," added Gaillard.
Denmark went on to win the tournament in Sweden after beating Germany 2-0 in the final.
Spain and second-placed Sweden qualified for this summer's finals in Austria and Switzerland from Group F, with Nigel Worthington's side missing out.
"We have heard nothing about this," said Irish FA president Raymond Kennedy.
"There has been no communication and it is obviously an internal matter."
