Ghana defender Baba Rahman was flown to the Gabonese capital Libreville on Wednesday morning to undergo tests on the injury he suffered at the Africa Cup of Nations.
The Black Stars left-back was accompanied by the team's medical doctor Adam Baba as they travelled from the team's base of Port Gentil.
The defender suffered a knee problem during the Black opening 1-0 Group D win over Uganda.
With no MRI facilities in Port Gentil, the Black Stars player had to travel to Librevile for the tests to be carried out before the full extent of injury can be determined.
The player and Ghana's medical team had to travel by air early in the morning for the tests in Libreville.
Rahman left the field on a stretcher after falling awkwardly before half-time of the game.
