Lille goalkeeper Vincent Enyeama will miss Nigeria's Africa Cup of Nations qualifiers with Congo and South Africa.
Enyeama has been granted leave for the two opening matches of the 2015 Afcon qualifiers on September 6 and 10 due to family reasons.
"It's better we excuse him, instead of bringing him down here without him concentrating for the game. I have asked him to sort himself out and he can join us in the future. For now there is no replacement for him because there is no time to do that," Nigeria boss Stephen Keshi explained.
As of the end of Monday, eight players had arrived the Metropolitan Hotel camp of the Super Eagles in Calabar.
Locally-based Kunle Odunlami, Gbolahan Salami, Christian Osaguona and Azubuike Egwuekwe were joined by Godfrey Oboabona, Nosa Igiebor, Ramon Azeez and Uche Nwofor.
The team is still battling with the release of Chinedu Obasi by his club Schalke, who said they have submitted his passport to embassies in Germany in order to procure visas to pursue their Champions League campaign.
Team administrator Dayo Enebi Achor is said to be working hard at ensuring that all players are available for the game.
The team will commence training on Tuesday at the Abraham Ordia Pitch of the University of Calabar.
