Bernard Lama's role as head coach lasted just two months
Deputy Kenya coach Tom Olaba will take charge of next month's Nations Cup qualifier in Angola after Bernard Lama decided not to return to his post.
Frenchman Lama, who only took charge of the Harambee Stars in July, finally lost patience with the Kenya Football Federation (KFF) at the end of last week.
"Bernard Lama has decided not to come back," KFF secretary-general Dan Omino told BBC Sport.
"With the time left between now and the match with Angola (on 6-8 October), it does not give us enough room to consider the option of a new coach.
"A number of coaches, who followed the Lama situation, have sent in their CVs but as of now, we are concentrating on preparation for the match.
"Tom Olaba, who was recently appointed deputy coach, will finalise the preparation for the match against Angola."
The KFF will consider Lama's replacement as head coach only after the Group 6 qualifier in Luanda.
The former French international, who lost his only competitive match at home to Eritrea earlier this month, left Nairobi on 6 September, saying he would not return unless issued with a contract to sign by the KFF.
"I have had enough," Lama told BBC Sport from his home in Paris on Sunday.
"Two days ago, I talked with my friends and family and decided that my role with Kenya was over because the KFF had made no move to get me back.
"I may go back to Kenya in future on holiday or to do some academy work, because Kenya has good football but I will never do anything with the KFF."
"I don't think the future for Kenyan football is bright with this administration."
Lama, who co-founded the Diambars academy in Senegal with Patrick Vieira, plans to go back to his businesses, which also include the creation of a water factory in French Guyana.
The Frenchman, who won 44 caps and the World Cup with his home nation, was heavily critical of the KFF during his brief and ill-fated tenure.
He never signed an official contract and said that he did not have the right conditions to work - citing a lack of budget and the necessary criteria for success.
Kenya's defeat against Eritrea leaves them a tough task to qualify from Group 6, which also includes Swaziland and 2006 World Cup finalists Angola.
