"Zaki is a 100% fit and has resumed full trainings," Zamalek's doctor Abdullah George told FilGoal.com.
The international striker was included in Zamalek's squad for Africa Sports game in the second-leg of the CAF Champions League round of 32 but he missed the trip claiming injury.
George denied giving him the permission to stay in Cairo.
An anonymous source revealed that manager Ruud Krol will drop Zaki from next Thursday's game against Masri.
Ahmed Magdi and Mohamed Ibrahim are also doubtful for this game as both suffered from muscle strains after Africa Sports game.
Left back Ossama Hassan will also miss the tie purging an automatic ban.
And finally some good news as Gamal Hamza has totally recovered from injury and is ready to resume full action.
