The Egypt forward limped off the first half of Sunday's defeat to Ismaili and a scan on Monday revealed a knee ligament sprain.

"He has a lateral collateral sprain. He will probably be out for two weeks," Ahli chief medic Ihab Ali told FilGoal.com.

Geddo will definitely miss Ahli's upcoming league fixture against Wadi Degla on Thursday.

The 26-year-old enjoyed a fine form of late, scoring twice in the last four games with the Egyptian champions.
