Some Premier League clubs could be stopped from picking players for their next game after complaints about their failure to release them for World Cup qualifiers.
Fifa can ban players not released in an international window for a period of five days after the window ends.
Wolves' Mexican striker Raul Jimenez and Newcastle's Paraguay midfielder Miguel Almiron could be affected.
Championship side Blackburn Rovers' Ben Brereton, who plays for Chile, is also likely to be affected and could miss two games.
Sources have suggested other national associations are deciding whether to make similar complaints.
La Liga failed in an attempt to block Fifa adding an additional two days to the South American international windows in September and October, which was demanded by South American football's governing body Conmebol because of the backlog of matches in their World Cup qualification programme.
