After undergoing tests, Real Madrid's medical team diagnosed Rudiger with an injury to the rectus femoris muscle in his left leg. The team did not provide information on how long Rudiger will be out of action.

Rudiger, who is 32 years old, had knee surgery in April due to a partial tear in the external meniscus. He returned to action in June at the Club World Cup. This latest injury is a setback for Rudiger, who is an important player for Real Madrid.

Rudiger's injury may affect Real Madrid's performance in their upcoming matches. The team will need to adjust their strategies to compensate for the absence of one of their key players. We will have to wait and see how the situation develops.

Rudiger's experience and skills on the field will be missed by his teammates and fans. The team hopes that he will recover quickly and return to action soon.
