The Kenya international joined the Iranian club in November 2024 on a six-month contract that expires on Monday, June 30, with the club having an option to extend it for another year.
The 29-year-old had been without a club for about five months before moving to Iran after ending his one-year stay with his previous club, Al-Jabalain, in July 2024.
He has had a difficult stay at Esteghlal, grappling with injuries and match fitness that have seen him make only 12 appearances.
The club is highly unlikely to activate the one-year extension option on his current stay, terming it as “close to zero per cent” due to his “not so bright appearance history.”
