Ahli's injury problems ahead of the Cairo derby against arch-rivals Zamalek mounted after learning that Mohamed Barakat would not be available for Tuesday's clash. The influential midfielder missed Ahli's 1-1 draw with Ittihad on Thursday after picking up a hamstring injury and will not be able to recover in time for the game against the stuttering Zamalek. "Barakat may take up to 10 days to resume full training," a source close to the player, who refused to be named, told FilGoal.com on Friday. Leaders and defending champions Ahli, who eye a sixth successive triumph, will be deprived of some key players when they meet Zamalek, who are just one point above the relegation zone. Playmaker Mohamed Abou-Treika is out with a serious foot injury and Liberian striker Francis Doe faces three weeks on the sidelines due to a hamstring complaint. Holding midfielder Moataz Eno is ruled out of the rest of the season after damaging the anterior cruciate ligament in his knee. Injured striker Emad Meteb is facing a race against time to be fit for the tie against a team who last beat Ahli in 2007.
