Konstantinos Karetsas' Alarming Injury in Champions League Match

Konstantinos Karetsas’ Champions League night ended in alarming fashion, with the Borussia Dortmund teenager leaving the pitch on a stretcher during the first half against Villarreal.

The 18-year-old had just released a pass when he immediately signalled to the bench, raised his arm, and then went to ground with no opponent near him. Medical staff rushed on and treated him for several minutes, concentrating on his upper body as a quiet unease spread through the stadium.

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

Dortmund later moved to clarify the situation, announcing that Karetsas had been substituted “due to circulation problems.” The club confirmed he had been taken to hospital for further examinations, adding that he “is doing as well as can be expected given the circumstances.”

The incident came after a slightly disrupted build-up for the youngster. Karetsas had not taken part in full team training on the eve of the match, instead working in the gym. Head coach Niko Kovač had played down any concerns in his pre-match press conference, describing it as a normal adaptation of workload, with one or two players occasionally skipping the full session.

Karetsas only arrived at Dortmund this summer from Genk, part of a double swoop that also brought in compatriot Giannis Konstantelias. The club’s plans for their new attacking core have already been tested: Konstantelias suffered an ACL tear in late August, prompting Dortmund to bring in Nwaneri on loan from Arsenal to bolster their options.

On the night, the team managed to steady themselves after the early shock. A second-half brace from Serhou Guirassy drove Dortmund to a 3-2 victory over the La Liga side, a result that will please Kovač but won’t completely silence the concern.

For a club investing heavily in its next generation, all eyes now turn to the hospital reports on Karetsas and what they will mean for a season already forced to improvise.
