At least six new players including Kelechi Iheanacho, have touched based at the camp of the Super Eagles in Austria, ahead of their friendly game against Cameroon on Friday.
Aside from Iheanacho, Oghenekaro Etebo, John Noble, Abraham Marcus, Emmanuel Anayo, and Abdullahi Shehu are now in camp.
The number of players in camp has increased to 17.
Others in camp are Maduka Okoye, Alex Iwobi, Wilfred Ndidi, Chidozie Awaziem, Jamilu Collins, Terem Moffi, Peter Olayinka, Samson Tijani and Valentine Ozornwafor
Their arrival is a massive boost for Super Eagles manager Gernot Rohr, who has been forced to deal with many withdrawals.
Nigeria take on Cameroon in a doubleheader friendly encounter, with the first match taking place on Friday before the second game on Tuesday.
The Super Eagles have met their arch-rivals 22 times, winning 11 times and losing just four games, with the rest ending in draws.
