Ahly midfielder Shehabeddin Ahmed sustained a muscle injury during the 1-0 win over Ghazl El-Mahalla in the Egyptian Premier League opener on Saturday and may not be fit for the coming clash against Wadi Degla in the second matchday on Sunday. "Medical scans have showed that Shehabeddin is suffering from a muscle injury," read a statement on Ahly's official website on Monday. "The injury may sideline the midfielder in the coming game against Wadi Degla next Sunday." Ahly, winners of the 2011 Premier League, opened the new campaign with an easy 1-0 victory over Ghazl El-Mahalla as the competition finally kicked off after months of wrangling over security concerns.
