The Malian striker will be out of action with a strained left oblique muscle.
He injured in the match against Naft Masjed Soleyman and also missed Tehran derby, where Esteghlal lost to its arch-rival Persepolis 1-0 in Tehran’s Azadi Stadium.
It will be a big injury blow for Esteghlal since the team has scored just two goals in four matches.
Esteghlal will meet Zob Ahan on Thursday in week 5 of Iran Professional League.
