U23 coach Samson Siasia is mulling replacing injured Segun Oduduwa with either Super Eagles star Godfrey Oboa-bona or Kenneth Omeruo for the Rio Olympics.
Oduduwa has been ruled out of the Olympics in August after he dislocated his knee in training and he will be out after surgery for as long as a year.
Turkey-based Oboabona is 25 and he will therefore feature in Rio as one of three over-aged players allowed for the competition.
Omeruo, on the other hand, is 22 and so he is eligible for the football event in Brazil.
Siasia says he will announce his decision soon.
