Al-Ittihad superstar, Karim Benzema, had to watch his team put three goals past Al-Wehda from the bench after hobbling off the field just before half-time.
The Frenchmen landed awkwardly after challenging for a header inside the Wehda box and immediately went down holding his left leg.
The World Cup winner, who is one of the biggest names in football, joined Ittihad in a summer spending spree of the Saudi Pro League’s biggest clubs.
The club said Benzema suffered a muscle injury and will undergo further medical examination, without providing a timeline for the player’s return.
The striker is an important part in Ittihad’s plans to retain the league title this season.
