Acute Circulation Issues Force Konstantinos Karetsas Off on Stretcher
Midfielder Drops to Turf Without Contact in the 23rd Minute
Playing in Dortmund, the 18-year-old midfielder dropped to the turf in the 23rd minute following an ordinary short pass, with no opposing player near him at the time. According to match reports from the Deutsche Presse-Agentur (dpa), Karetsas immediately reached for his chest and placed his left arm across his face in obvious distress.
Medical staff rushed onto the grass with a stretcher within moments. After several minutes of on-field treatment, paramedics carried the young Greek international off the pitch as supporters inside the stadium offered supportive applause. Borussia Dortmund later confirmed that Karetsas was conscious and transported to a nearby hospital for thorough medical evaluations, adding that he was doing as well as could be expected under the circumstances.
