Chelsea winger Victor Moses, who missed Nigeria's opening game, is expected to enter the Africa Cup of Nations fray against Zambia today.
The winger's return from injury is welcome news for the Super Eagles, who take on the defending champions four days after being held to a 1-1 Group C draw by Burkina Faso.
That surprise stalemate has added emphasis on an already tough assignment for coach Stephen Keshi's side.
"Victor trained well yesterday and, hopefully, will be okay to play. He will bring his desire to the side," said Keshi.
Keshi stressed the importance for his players to concentrate right to the bitter end against Zambia.
He described the mood in the Super Eagles camp as "tremendous" before adding: "We know the job we have to do".
