The Stars took part in no friendly matches during the November FIFA worldwide break with Zambia date suffering last minute cancellation by Football Kenya Federation (FKF).
Burkina Faso didn't qualify for the World Cup but moved up 11 places to become sixth in Africa, while Senegal rose to 23rd - their highest-ever position on the global ladder - on the back of securing a first World Cup place since 2002.
What that means is that playing friendlies has a negative effect on a nation's ranking, as they're worth just one point in terms of match importance, compared to 2.5 points for a qualifier or four points for a World Cup match.
The latest rankings, which was published on FIFA's official website, sees the Eagles assume 50th position in the world and 8th in Africa.
Mexico at No 16 is best of the teams from Concacaf., while Senegal moved up nine to be Africa's best at No 23.
A 1-1 draw at lowly Algeria, who were 66th last month, will account for this huge tumble.
The Democratic Republic of Congo remained fourth and Herve Renard-coached Morocco climbed two places to fifth after defeating the Ivory Coast to book a World Cup slot in Russian Federation.
The team was largely expected to soar on the rankings on the back of their rampant form, but alas, the reverse was the case as they've now plunged to 50th in the world, behind the likes of Greece, Montenegro and Cameroon who failed to make the Russian Federation party. Tunisia (27), 3. Egypt (31), 4.
