The on-loan defender was forced off during the Black Stars' win on Tuesday and his national team boss believes it could rule him out of the tournament
Ghana head coach Avram Grant stated Baba Rahman's prospects of playing any further part in the Africa Cup of Nations are "50-50" after the left-back suffered an apparent knee injury during the opening 1-0 Group D win over Uganda.
Rahman, who is on loan with Bundesliga outfit Schalke from Chelsea, left the field on a stretcher having twisted the joint awkwardly shortly after Andre Ayew put the Black Stars in front from the penalty spot.
