Ahly striker Ahmed Abdel-Zaher will be out of action for two weeks due to injury, the club announced on Monday.
"Abdel-Zaher will be sidelined for two weeks," Ahly's football director Wael Gomaa told the club's official website.
Abdel-Zaher suffered a knock in the chest during Ahly’s Sunday 2-1 comeback victory over Tunisia’s Club Africain in the first leg of the CAF Confederation Cup round of 16.
Abdel-Zaher scored Ahly's first goal in the second half before being directly substituted due to his injury.
Late on Monday, the player underwent a surgery to remove fluids accumulated in his lungs.
"The doctor ordered the striker to avoid travelling by airplanes for two months," Gomaa added.
Accordingly, the player will miss the return leg match against Club Africain on 6 June in Tunisia besides missing all possible away African games during these two months.
Thirty-year-old attacker Abdel-Zaher joins a long list of Ahly injured players like Walid Soliman, Moeman Zakareya, Mohamed Hani, Mahmoud Hassan 'Trezeguet' and Hossam Ashour.
Ahly, who are bidding to defend their Egyptian Premier League title, lie third in the league table with 55 points, eight behind leaders and rivals Zamalek.
