Obasi earns Nigeria call-up
Obasi, 23, had been left out of the original 23-man squad named by Nigerian coach Shaibu Amodu at the weekend after Obafemi Martins passed a late fitness test.
Amodu had a change of mind after the deadline for the submission of his squad and requested permission to include the Hoffenheim player in place of Eneramo, the Nigerian Football Federation said.
Nations Cup regulations normally allow teams to make changes to their squads up to seven days before their opening game of the competition.
Nigeria play defending champions Egypt in their Group C opener in Benguela, Angola on January 12.
