Zamalek defender Hamza Mathlouthi had successful surgery in Germany to fix a torn anterior cruciate ligament (ACL), the team announced on Wednesday.

The Tunisian international injured his right knee on January 23 during a Premier League match against Modern Sport FC, which Zamalek lost 1-0. He was diagnosed with the injury the following day.

“Mathlouthi had successful ACL surgery in Germany and is doing well,” said Mohamed Osama, the team doctor. “He will start his rehabilitation program soon,” he added. Mathlouthi’s injury is a big loss for the White Knights, as they will be missing one of their key defenders for a long time.

Since joining Zamalek in 2020 from CS Sfaxien in Tunisia, the 32-year-old has scored five goals in 152 games. He played 13 times this season before the injury.

Currently, Zamalek SC is in third place in the Egyptian League with 20 points from 11 games, four points behind the leaders, Pyramids FC.
