Konstantinos Karetsas was forced off during Tuesday's UEFA Champions League clash with Villarreal after suffering circulatory problems. He is now on his way to hospital for further tests, while Borussia Dortmund say the 18-year-old Greece international is doing well under the circumstances.
Dortmund's update on Karetsas
The club's report gives the key details and not much more. Karetsas was taken off during the match, the issue was described as circulatory problems, and further tests are now pending.
Dortmund's statement also offered the first sign of reassurance, saying he is doing well under the circumstances. That is the part supporters will focus on first, because the immediate concern is his health, not the football.
A small early spell at Dortmund
The scare comes very early in his Dortmund spell. The club said Karetsas was making his fifth appearance for the side after joining from Genk in the summer, while the stats pack shows 4 appearances across the 2026 season sample and 211 minutes played.
He has already managed 1 assist in that limited time, and his most recent Dortmund outing carried a 7.7 rating. None of that changes the bigger issue now, but it does show he had been involved before Tuesday's stoppage.
Dortmund's next match is against SC Paderborn 07 on 12 September, and the club will be waiting on those hospital tests before anything else matters.
