Galatasaray midfielder Oghenekaro Etebo, who is 25 today, goalkeeper Maduka Okoye and Genk striker Paul Onuachu are among the early arrivals at the Super Eagles training camp in Benin City.
Other players in camp include captain Ahmed Musa and Leicester City striker Kelechi Iheanacho.
Etebo missed last month’s friendlies against Algeria and Tunisia in Austria last month due to injury.
It has been a great weekend for Sparta Rotterdam shot stopper Okoye, who kept a clean sheet as his Dutch club won 2-0 at RKC.
Onuachu remains the leading scorer in the Belgian Jupiler Pro League with nine goals.
He is a late replacement for injured FC Nantes winger Moses Simon.
