The Indomitable Lions of Cameroon will begin Africa Cup of Nations which kicks off on January 9, 2022.
Players summoned by head coach Toni Conceçaio are expected in camp latest 6pm on Monday with effective training on Tuesday.
However, the team will be without midfielder Jean Onana who has been ruled out after picking up an injury while playing for his French side, Bordeaux.
A natural replacement was supposed to be midfielder Arnaud Djoum but the player is reportedly nursing an injury and head coach Toni Conceçaio has to now look at other options.
On the other hand, defender Harold Moukoudi will gradually be phased into the team after just recently returning to training following an injury that has kept him on the sidelines for several weeks.
