Ghana are likely to miss Emmanuel Agyemang-Badu for Wednesday�s Nations Cup semi-final clash against Zambia.
The Udinese midfielder missed the team�s training session at the Estadio de Bata on Tuesday due to a knee injury.
Badu, voted man-of-the-match in the quarter-final clash against Tunisia, had packed ice on his right knee after the match.
He has started in all of Ghana�s four matches at the tournament.
He is appearing at the Nations Cup finals for a second time and scored his first goal against Guinea in the Group stages.
