FIFA has issued all 25 Caribbean football associations with a 48 hour deadline to explain if they had any part in the Trinidad bribery rort, or face being banned for life.
FIFA says that any person with relevant information who does not come forward 'will be subject to the full range of sanctions.'
FIFA banned former Asian Football Confederation president Mohamed bin Hammam on Saturday after a two day hearing where they established he had offered $US40,000 cash bribes to Caribbean officials to back his presidential bid.
The deadline for evidence to be submitted is Wednesday.
