Ahli playmaker Mohamed Abou-Treika will undergo a scan on Monday to learn whether he can return to full training. The Egypt international has been suffering from a recurring knee problem that ruled him out of the Pharaohs' four World Cup qualifiers in June. Ahli fans fear their star might miss the team's crunch Champions League encounter against arch-rivals Zamalek next month. However, Monday's scans would determine whether Abou-Treika has a chance to feature in the anticipated game. German knee surgeon Andreas Imhoff has recently advised Abou-Treika to get adequate rest in order to fully recover.
