Karetsas Returns to Borussia Dortmund Training After On-Field Collapse

The club says he has rejoined group sessions following hospital checks; Dortmund has not disclosed a formal diagnosis or confirmed his availability for upcoming matches.

Overview

Konstantinos Karetsas collapsed during his Champions League debut and was stretchered off with suspected circulatory problems before being taken to hospital.
Dortmund confirmed he completed individual training earlier in the week and then rejoined the full team for a group session.
Karetsas visited his former club Genk and appeared in a video saying medical tests showed “everything is fine” and that he needs time to adjust to intensity.
Borussia Dortmund has not released a formal medical diagnosis and has not said whether he will be available for the next games.
The 18-year-old was a high-fee signing from Genk and his monitored recovery will affect Dortmund’s midfield options as the club manages other recent absences.
