The Confederation of African Football (Caf) will announce which country will host the 2019 Africa Cup of Nations on Tuesday – a day earlier than expected.
No reason has been given for Caf’s sudden change of timing, with the announcement having been scheduled for Wednesday 9 January.
Egypt and South Africa have submitted formal bids to host the finals.
Original host nation Cameroon was stripped of staging the tournament in November because of slow preparations.
CAF has since offered Cameroon the chance to stage the finals in two years’ time, which has meant that the original hosts for both the 2021 and 2023 finals have been asked to delay their tournaments.
Ivory Coast, which was set to host the 2021, has protested the decision at the Court of Arbitration for Sport.
Guinea’s football federation announced on Monday that it has agreed to move its staging of the Nations Cup from 2023 to 2025.
The successful bidder for this year’s finals will have just six months to prepare for the 24-team finals, which are scheduled to run between 15 June and 13 July.
Tuesday’s announcement will take place in the Senegalese capital Dakar, which will host Caf’s annual awards ceremony later in the day.
