Nigeria suffered another blow to their hopes of qualifying for next year's World Cup finals after suffering a shock 1-0 defeat against Sierra Leone on Saturday.
Sidque Mansaray of local team Eastern Lions scored the only goal of the game after 25 minutes in front of 40,000 fans in Freetown.
It was Sierra Leone's first win in five African zone group two qualifying games.
Nigeria are two points behind joint leaders Liberia and Sudan, who meet in Monrovia on Sunday, having played one game more.
