Zamalek's striker Amr Zaki confirmed on Monday that he will not be able to play in Saturday's CAF Champions League preliminary round clash against Tanzanian side Young Africans, after being diagnosed with a leg injury. "The doctor told me that I am suffering from a hamstring tear which needs two weeks of treatment and rehabilitation," the 28-year-old marksman told Ahram Online. Zaki left Sunday's team training after feeling hamstring pain, and scans revealed that he was seriously injured. The international striker made a good return to the White Knights after three months of absence due to his problems with the club's board, scoring the equaliser for Zamalek in their 1-1 draw against Young Africans in the first leg. Zamalek, who are looking for its first continental title since 2002, will meet Young Africans on Saturday in the military academy stadium behind closed doors.
