Overview

• During Schalke’s 2–1 win in Bielefeld, a 69th-minute collision left Arminia striker Joel Grodowski briefly unconscious after contact with goalkeeper Loris Karius.
• Schalke defender Nikola Katic immediately placed Grodowski in the recovery position before medical staff reached the scene.
• Grodowski regained consciousness, embraced Karius and wanted to continue playing, but he was substituted as a precaution.
• Schalke coach Miron Muslic praised Katic for reacting well in a chaotic moment, and Bielefeld coach Mitch Kniat said doctors removed the player under a zero‑risk approach.
• Reports noted Katic suffered a concussion in August after a separate head blow, providing context for his quick intervention.
