Overview

• The incident occurred in the 69th minute when goalkeeper Loris Karius punched for the ball and struck Arminia forward Joel Grodowski.
• Schalke defender Nikola Katic immediately placed Grodowski in the recovery position before medical staff reached the pitch.
• Grodowski soon regained consciousness, embraced Karius, asked to continue, and was substituted as a precaution.
• Schalke coach Miron Muslic praised Katic's calm reaction, and Bielefeld coach Mitch Kniat said Grodowski was doing well under a zero‑risk protocol.
• Reports noted Katic previously suffered a head injury and a later‑diagnosed concussion in August, while a separate single‑source claim about an additional maneuver remained uncorroborated.
