Incoming Cameroon coach Volker Finke will take charge of the team for Sunday’s friendly against Ukraine.
The German was set to begin his new role after June’s World Cup qualifiers against Togo and DR Congo.
But with the man he will replace, Jean-Paul Akono, recovering from a heart attack, Finke has stepped into the role earlier than expected.
However, it is not clear if Akono could return for Cameroon’s Brazil 2014 qualification matches.
Akono has said he is well enough to be in Kiev but his name was not included on the list of the official delegation travelling to Ukraine.
And it seems that there is no end yet to the power struggle between Akono and the Cameroon Football Federation that has been ongoing since the governing body advertised the coach’s job without his knowledge.
Cameroon’s match against Ukraine serves as preparation for their Group I matches against Togo in Lome on 9 June and DR Congo on 16 June – and it is also now a chance for Finke to take a first look at his players.
He will, though, have to wait to select big-name players Samuel Eto’o, Alex Song, Allan Nyom, Charles Itandje and Benoit Assou-Ekotto as they are all unavailable.
Cameroon skipper Eto’o is set to play for Anzhi Makhatchkala in Saturday’s Russian Cup final, while Itandje is involved in play-offs with his club Paok Thessalonique Greece until 2 June.
Barcelona midfielder Song and on-loan Granada defender Allan Nyom will play the last day of the Spanish League on 1 June.
And Assou-Ekotto picked up an injury when playing for his club Tottenham in a friendly against Jamaica recently, but is expected to be fit to face Togo in Lome on 9 June.
All five will join up with the Indomitable Lions squad after the friendly to train at the Caf Technical Centre in Mbankomo in the outskirts of Yaoundé.
