BVB subsequently confirmed the injury, with managing director Lars Ricken saying, "This news hits us hard, because Giannis has already shown in a very short time why we see him as a great player for Borussia Dortmund." The injury occurred when Konstantelias twisted his left leg awkwardly in the turf during first-half stoppage time. He was taken off early in the second period.
Bundesliga reports that Konstantelias has undergone a successful operation, with his doctor Thore Zantrop sharing an image of the midfielder in the aftermath on his Instagram page. The Greece international will still be out of action for several months, but can now start the road to recovery and get back onto the pitch as soon as possible.
