KAA Gent wonderkid, Gift Orban is set to make his debut for Super Eagles against Leone Stars at the 18 June AFCONQ clash in Monrovia, Liberia.
Orban is having a fantastic season in the Belgian top tier netting 15 goals in just 14 matches.
The 20-year-old striker has netted a total of 19 goals in all competition with a notable hat trick against rivals Cercle Brugge.
Orban, who also played for Stabaek Fotbal, had earlier rejected a call up from the Nigerian team due to personal reasons.
Nigeria will play Sierra Leone in June before honouring their final tie against São Tomé and Principé in September.
A win for Nigeria will see them earn a spot for AfCON in Ivory Coast next year.
The match is also an all important one for Sierra Leone who have only 5 points after four games.
