The 31-year-old suffered a minor injury in last weekend's 4-2 win over Gaish, which provoked speculation that backup keeper Mohamed Abdul-Monsef will take over.
However, Zamalek chief medic Mostafa Al-Monayeri confirmed to the club's official site that Al-Sayed will be fit for the Olympic visit.
Young duo Hazem Emam and Ahmed Al-Merghani are also declared fit for the game against the league strugglers.
Meanwhile, Al-Monayeri confirmed that midfielder Mohamed Aboul-Ella is likely to miss the Olympic clash after sustaining a foot bruise during Tuesday's training.
The player, who missed the Gaish win also due to injury, will undergo further tests on his foot on Wednesday.
