Further Setback for Dortmund's Greek Contingent

The incident with Karetsas comes as another blow for Dortmund, who recently saw his fellow Greek summer signing, Giannis Konstantelias, suffer a severe ACL injury in his Bundesliga debut. Konstantelias joined Borussia Dortmund from PAOK on August 17, 2026. He sustained a torn anterior cruciate ligament in his left knee during his Bundesliga debut against Hamburger SV on August 29, 2026, and is expected to miss the majority of the current season.

Karetsas, born on November 19, 2007, and currently 18 years old, is a right winger or attacking midfielder. His early performances for the German giants had shown considerable promise, making his Champions League debut a highly anticipated event before the unfortunate turn of events.

The football world awaits further updates on Konstantinos Karetsas' condition, with hopes for a swift and full recovery for the talented youngster. His well-being remains the primary concern for Borussia Dortmund and fans globally.
