Tetteh loan agreement has been extended by the SLFA executive committee and he will be in charge of Sierra Leone’s two legged tie against Gabon in the 2017 Africa Cup of Nations qualifiers.
However, the Gabon match is a no points scoring clash for the two sides as Gabon are hosting January's finals which exempts them from playing in the qualifiers. Nevertheless, they are using the tie as a friendly fixture.
He said: "After the Gabon matches we will decide whether to make it permanent or not."
The 59-year-old coach who was contracted back in August 2015 took charge of Leone Stars matches against Ivory Coast and Sudan in the 2017 Nations Cup Group I qualifiers and also the 2018 two-legged World Cup qualifiers in which Chad eliminated Sierra Leone on away goals rule.
Tetteh and his boys will host the Gabonese in Freetown on March 28th just three days after the first leg in Franceville on 25th March.
The Gabon tie will be the first Leone Stars International match to be played in Freetown since the African Football governing body, CAF lifted the international ban on all footballing actions following the Ebola scourge in the country.
