Gyan returned to team training on Wednesday from a thigh injury and coach Milovan Rajevac will be able to call on the Stade Rennes striker.
Gyan scored 1-0 winner in the quarterfinal against hosts Angola. His thigh problem led to fears that he might have to sit out the game against the Super Eagles.
Gyan's availability will come as a great relief to the Serbian coach, who has lost the services of Chelsea midfielder Michael Essien for the tournament.
Several other regulars like Stephen Appiah, John Mensah, John Paintsil and Laryea Kingston failed to make the trip to Angola due to injuries.
