**Dortmund’s Karetsas Hospitalised After Collapsing in Champions League Match**
Borussia Dortmund's promising midfielder Konstantinos Karetsas was hospitalized following a concerning incident during his UEFA Champions League debut against Villarreal on September 9, 2026. The 18-year-old Greek player collapsed on the pitch just 25 minutes into the match, prompting immediate medical attention.
According to a statement released by Borussia Dortmund, Karetsas experienced circulatory problems, which led to his abrupt exit from the game. The club reported, “Kosta is doing well under the circumstances and is on his way to the hospital for further tests.” At the time of the incident, the match was still scoreless, with Dortmund eventually securing a 3-2 victory.
Witnesses noted that after passing the ball to a teammate, Karetsas signaled to the referee, indicating that he was in distress before sitting down on the grass. Medical staff quickly attended to him, and he was subsequently transported off the field on a stretcher.
Dortmund goalkeeper Gregor Kobel expressed hope for Karetsas's recovery, stating, “I hope and I think that everything is OK, and I hope that he’s back and fit with us soon.” The club and fans alike are anxiously awaiting further updates on his condition.
Karetsas joined Borussia Dortmund in the off-season, making headlines as one of the club's marquee signings. He was acquired for approximately $34.9 million from Genk, where he had an impressive season, contributing 11 assists in 28 appearances in the Jupiler Pro League. His skill set, characterized by creativity and intelligence on the field, was highlighted by Dortmund's sporting director Ole Book, who noted, “With his creativity and game intelligence, Kos will enrich our team.”
In addition to his club success, Karetsas has also represented Greece at the international level, making his debut in March 2025 and scoring three goals in ten appearances. His decision to play for Greece came after previously representing Belgium's youth teams.
The incident adds to a challenging season for Dortmund, as fellow summer signing Giannis Konstantelias, 23, is currently sidelined with an ACL injury that is expected to keep him out for the remainder of the season. The team will be closely monitoring Karetsas's recovery as they continue their campaign in both domestic and European competitions.
As fans and teammates rally around Karetsas, the football community remains hopeful for a swift and full recovery for the young talent. Further updates from Borussia Dortmund are anticipated as they provide more information on his health status in the coming days.
