CAF has announced that it will now allow one month for countries interested in hosting the tournament to submit their official bids.
African football's governing body (Caf) says it is because of delays in the progress of Cameroon's preparation for the tournament, due to start in June.
CAF inspectors recently traveled to the country, which last hosted the tournament in 1972, to check security, infrastructure, stadiums, and accommodation.
Friday's CAF executive committee decision was mainly drawn from the unsatisfactory report of inspection visits of the security committee from October 27 to November 1 as well as a report of the inspection visit from November 11-15.More news: Fed minutes: Further hike "warranted soon", debate opened on pause
A report of the last two inspection visits to central African state Cameroon will be made during the meeting.
Also, speculations are rife that the AFCON 2019 could now be staged in Morocco or South Africa.
Morocco immediately said it was ready to replace Cameroon, beginning more than a year of claims and counter-claims that CAF intended taking the tournament away from Cameroon and giving it to the north African country.
Though the tournament is scheduled to be held in June/July, its expansion from 16 teams to 24 means more facilities would have to be made available by the host nation.
Morocco, who lost out to a United States/Mexico/Canada bid for the 2026 World Cup, have regularly been reported as possible replacements.
