Giants Al Ahly will host Ghanaian side Berekum Chelsea in Saturday's CAF Champions League Group B tie without duo Mohamed Abou Treika and Emad Meteb.
The Cairo giants have allowed the two players to remain with Egypt's Olympic who have progressed to the quarter-final.
Ahly face Chelsea at the Military Stadium on Saturday-the same date Egypt's Under-23 will play Japan.
"After consulting manager Hossam Al-Badri and chairman Hassan Hamdi, we have decided to leave Abou-Treika and Meteb with Ahmed Fathi until the end of the Olympics,'' Ahli football director Sayed Abdul-Hafiz told the club's website.
"Ahli is keen to support the national team after qualifying for the quarter-finals, even though our team really need both players."
Ahly have got three overage players including right-back Ahmed Fathi who is suspended for the club's upcoming CAF Champions League match.
The six-time champions lead Group B with maximum points from wins over TP Mazembe and Zamalek.
