Worry for Dortmund as Karetsas Stretchered Off in Champions League Clash

Borussia Dortmund’s 3-2 win over Villarreal came at a cost, and it was a worrying one. Konstantinos Karetsas, one of the club’s brightest young prospects, left the pitch on a stretcher after a troubling first-half incident that briefly silenced the crowd and shifted the tone of the night.

The 18-year-old had just released a pass when he immediately raised his arm towards the bench, signalling distress before sinking to the turf. Medical staff rushed on and worked on him for several minutes, concentrating on his upper body as teammates and opponents watched on, visibly concerned.

He was eventually taken off on a stretcher and headed straight down the tunnel to the locker room, replaced by Ethan Nwaneri in the 27th minute.

Dortmund later moved to clarify the situation. The club said the substitution was “due to circulation problems” and confirmed Karetsas had been taken to hospital for further examinations. The update added that he “is doing as well as can be expected given the circumstances,” a line that will offer some relief but no real certainty yet.

The incident did not come completely out of nowhere. Karetsas had not taken part in full training with the rest of the squad on the eve of the game, instead working in the gym. Manager Niko Kovač had played down any concerns in his pre-match press conference, describing it as a normal variation in preparation, with one or two players occasionally following individual programmes rather than joining the full session.

Karetsas only arrived at Dortmund this summer from Genk, part of a Belgian-Greek influx that also brought in his countryman Giannis Konstantelias. That particular storyline has already taken a harsh turn: Konstantelias suffered an ACL tear in late August, a serious setback that forced Dortmund back into the market. The club responded by bringing in Nwaneri on loan from Arsenal to help cover the creative burden.

On the night, Nwaneri’s introduction came much earlier than planned, under far more worrying circumstances than a simple tactical tweak.

The match itself swung wildly. Villarreal pushed Dortmund hard, but a second-half brace from Serhou Guirassy ultimately dragged the Bundesliga side over the line in a 3-2 victory. It should have been a statement win, a marker in Europe. Instead, much of the post-match conversation circled back to the teenager who had left the pitch before the half-hour mark.

For a club that has built its modern identity on nurturing young talent, the sight of Karetsas being stretchered away so early in his Dortmund journey felt particularly stark. With Konstantelias already sidelined long term and Nwaneri drafted in to plug one gap, the coming days will tell whether this is a brief scare or the start of another complicated chapter in Dortmund’s season.
