Borussia Dortmund’s Karetsas Hospitalised After Circulation Scare in Champions League Debut

Borussia Dortmund’s 18-year-old midfielder Konstantinos Karetsas was stretchered off the pitch and taken to hospital after suffering circulatory problems during his UEFA Champions League debut against Villarreal on Tuesday evening. The Greek international, a marquee summer signing from Genk, collapsed without any contact from an opponent in the 27th minute, prompting immediate medical attention and visible concern from teammates and staff.

Dortmund confirmed the situation in a brief statement, saying Karetsas was stable under the circumstances and undergoing further tests. The incident cast a shadow over what became a dramatic 3-2 win for the Bundesliga side.

What happened on the pitch

Karetsas, who had started the match at Signal Iduna Park, appeared to be in normal rhythm while dribbling and completing a pass. Moments later, he sank to the turf and raised his arm to signal for help. Medical staff rushed onto the field and treated him lying down before carefully lifting him onto a stretcher. The 18-year-old was substituted for Arsenal loanee Ethan Nwaneri.

Former Dortmund defender Mats Hummels, working as an analyst for Amazon Prime Video, expressed his concern during the broadcast. “When the doctors did not look at his legs at all and were only focused on his upper body, it sent a shiver down my spine,” Hummels said. “We would not wish something like that on anyone. Those are really horrible scenes we had to see there.”

Official confirmation and hospital tests

Dortmund released a statement shortly after the match: “Konstantinos Karetsas had to leave the pitch in the game against Villarreal due to circulation problems. Kosta is doing as well as can be expected given the circumstances, and he is on his way to the hospital for further examinations.”

Goalkeeper Gregor Kobel also spoke to Amazon Prime, saying: “I hope and I think that everything is OK and I hope that he’s back and fit with us soon.”

The club has not yet provided a timeline for his return or a specific diagnosis, pending the results of those hospital tests.

A significant signing facing early adversity

Karetsas joined Dortmund from Genk in the summer for a reported fee of €30 million ($34.9 million), one of two high-profile Greek arrivals alongside Giannis Konstantelias, who moved from PAOK for €26 million ($30.2 million). While Karetsas was making his fifth appearance for the club, Konstantelias suffered an anterior cruciate ligament injury on his Bundesliga debut last month, likely ending his season.

The back-to-back health setbacks for Dortmund’s Greek prospects add an emotional layer to what has been an ambitious squad rebuild. Karetsas, a former Belgium youth international who switched allegiance to Greece, was seen as a key creative piece for the Black-and-Yellows going forward.

Match context and aftermath

Tuesday’s match was Karetsas’ first Champions League appearance. The game itself remained scoreless at the time of his departure. Dortmund took the lead after the break when Villarreal defender Renato Veiga turned the ball into his own net. Villarreal equalised through Santiago Mourino in the 66th minute, but Serhou Guirassy scored the winner to secure a 3-2 victory for the hosts.

Despite the positive result, the focus after the final whistle remained on Karetsas’ condition. Dortmund fans and neutrals alike will be hoping for a full recovery ahead of the club’s next fixture, a Bundesliga meeting with Paderborn on 12 September.

Key facts

What it means for Dortmund

For a club that has built its reputation on developing young talent, seeing one of its brightest prospects stretchered off in alarming fashion is a sobering moment. While the immediate medical updates are reassuring, the incident will raise questions about player workload and medical screening protocols. Dortmund’s medical staff will now await full test results before determining the next steps for Karetsas’ recovery and return to training.

The team will travel to Paderborn on 12 September for their next Bundesliga outing. Further updates on Karetsas’ condition are expected once hospital examinations are complete.
