Borussia Dortmund secured a 3-2 victory, but the match was overshadowed by a medical emergency involving 18-year-old talent Konstantinos Karetsas, who suffered circulatory issues during the first half and required a stretcher to leave the pitch at Signal Iduna Park.
Circulatory Issues Force Early Exit for Karetsas
The incident occurred in the 25th minute of the match when Konstantinos Karetsas abruptly stopped playing, lay down on the turf, and signaled for immediate medical assistance. Club medical personnel rushed to the pitch, attending to the teenager before he was carried off on a stretcher amid freezing scenes in Dortmund.
Borussia Dortmund provided an update on the player’s condition via social media shortly after the incident. According to the club’s statement, Konstantinos Karetsas had to leave the pitch due to circulatory issues. The club confirmed that, under the circumstances, Kosta was doing well and heading to a hospital for further examinations.
High-Stakes Debut Overshadowed by Medical Scare
The fixture marked a significant milestone for Karetsas, who arrived at Borussia Dortmund in August from Genk for a reported fee of 30 milionů eur (asi 756 milionů korun). The teenager was making his debut in the UEFA Champions League when the medical emergency halted play.

Former Germany defender Mats Hummels, working on-site as a television expert following the conclusion of his professional playing career, described the tense atmosphere at the stadium. According to Hummels, watching the medical staff focus entirely on the upper body rather than the players’ legs sent a chill down his spine. The television commentator noted that such an event is something no one wishes to see, especially not a young player experiencing his first minutes in Europe’s premier club competition.
Match Context and What Comes Next
Despite the emotional shock of the incident, Borussia Dortmund managed to close out a 3-2 win. The club has not yet released a timeline for Karetsas’s return to training or detailed results from the hospital evaluations.
