A report suggests that Borussia Dortmund youngster Konstantinos Karetsas is set to miss several weeks of action.

Konstantinos Karetsas will reportedly have to spend several weeks on the sidelines after sustaining an ankle injury during Borussia Dortmund’s 0-0 Bundesliga draw with 1. FC Union Berlin on Saturday.

According to Ruhr Nachrichten, the 18-year-old is expected to be out at least until the next international break in mid-November.

Karetsas returned from Berlin on crutches on Saturday evening, with the exact nature and severity of the injury yet to be determined by the club.
