FIFA says it is giving Nigeria one last chance to avoid a "lengthy" ban that would prevent the reigning champion from defending its title at next year's African Cup of Nations.

FIFA wants a court order nullifying recent Nigeria Football Federation elections to be rescinded, regarding it as government interference in football, which isn't allowed under the world body's rules.

FIFA says Nigeria has until midday Friday Nigerian time to prove that the court order has been withdrawn and the NFF is able to work "without any hindrance." If Nigeria doesn't comply, FIFA says it will be banned from international football at least until FIFA's Congress in May next year.

That would mean Nigeria is thrown out of the ongoing qualifying competition for the tournament in January and February.
