Zidan�s second-half introduction in the recent Bundesliga clash at Kaiserslautern only lasted for eight minutes as he received a fierce knock to his ribs in the 1-1 draw.
�I had a scan and it showed that the injury is not serious. It was just a knock in my ribs,� Zidan told the Egyptian FA�s website.
�The doctor told me to rest for now until the pain goes away, but I should be fully fit to play in the South Africa match.�
Zidan, who only appeared twice for Bundesliga leaders Dortmund so far this term, remains doubtful for next weekend�s match against St. Pauli at home.
