Ahli striker Dominique da Silva is set to miss next week's Cairo derby against Zamalek after suffering another hamstring injury in the win over Arab Contractors. The Mauritanian, who missed spells of the current season because of his nagging hamstring, appeared to have pulled the muscle midway through the second half of the 2-0 win and it was confirmed that he will be out for at least 10 days. “It is not yet clear whether it is the same injury or a new one. This will be known after the scan,” Ahli doctor Ihab Ali told the club's website. “But he will surely miss the next couple of games against Masri and Zamalek.” Ahli visit Hossam Hassan's Masri on Wednesday as they clash with arch-rivals Zamalek a week later at Cairo Stadium.
