After the shock surrounding Konstantinos Karetsas, attention is now turning to his health. There are now initial findings from the examinations.
At Borussia Dortmund, hope is growing after the scare involving Konstantinos Karetsas that the 18-year-old could return soon. The medical tests following his collapse against Villarreal (3-2) have apparently not revealed any abnormalities so far. However, there is still no explanation for the sudden circulation problems.
According to information from BILD, Karetsas remained in hospital overnight and underwent thorough examinations there. The initial results reportedly showed no indication of a serious physical cause. For BVB, however, that does not mean the Greek will return to the training pitch immediately. Further examinations are expected to provide clarity first.
There is still speculation above all about what could have triggered the incident. Reports emerged in Belgium suggesting that a lack of fluids may have played a role. There has been no official confirmation of that so far. BVB sporting director Lars Ricken described the situation after the match as follows: “They were circulation problems that came out of nowhere. There had been no warning signs.”
Karetsas suddenly collapsed on the pitch during the Champions League clash with Villarreal. After receiving initial medical treatment, the Dortmund player was taken straight to hospital. However, his teammates had already received reassuring news during the match. BVB said the new signing was “doing as well as could be expected under the circumstances.”

Niko Kovac also informed his team about their teammate’s condition while they were still in the dressing room. “I told my players that everything is okay. They worry too,” the coach explained afterwards. When Karetsas will be available again remains unclear for now. At BVB, his health is expected to take priority over a quick return.
Accordingly, he is only likely to resume full training once the medical examinations have been completed and any possible risks have been ruled out. Whether he will be ready in time for Saturday’s Bundesliga home game against Paderborn (3:30 p.m.) is therefore uncertain. Still, the findings so far, which have shown nothing unusual, are at least an encouraging sign for Karetsas and Dortmund.
