Ahli captain Shadi Mohamed is a doubt for the derby clash against Zamalek next Friday with a knee injury. "I had a medical test and it proved I suffer from a knee injury," the international defender told FilGoal.com. Shadi was substituted during the game by Ahmed Al-Sayed who is back to action for the first time since the beginning of the year. "I don't know if I will play on Friday but I will have a fitness test tomorrow," added Shadi. Meanwhile, an internal source revealed that Mohamed Abou-Treika will be included in the squad for this crucial game. "The presence of Abou-Treika, even on the bench, will boost the team." The gifted playmaker has resumed full training since Sunday and is set to pass a fitness test on Wednesday morning.
