Giulia Gwinn injured herself in the first half in Friday evening's 2–0 win over Poland in connection with the back star making an important break in her own penalty area.
The message is a nightmare for Germany, which has an stated goal of taking gold in the European Championship.
The Bayern Munich star has had two cruciate ligament injuries earlier in her career and therefore missed the World Championship 2023 – this time, however, it was not as serious.
The German association writes on its website that Gwinn "is expected to be out for several weeks".
Sweden meets Germany in the group stage finale in Zurich next Saturday. Without the right-back Gwinn, the Germans lose strength.
She is incredibly important for their national team. There is no stop for her, she steps on the gas on the right wing, says Linda Sembrant after Sweden's Saturday training at the national team base in Cham.
The 38-year-old blue and yellow veteran has been a teammate with Gwinn in Bayern Munich since last year.
A fantastic person and player. She has missed championships before, it hurt my heart to see her (injured) on the pitch, says the center back.
Of course, it's a loss for them (Germany), but above all, I suffer with her personally.
The German association writes that Uefa's rules do not allow any replacement to be brought in as substitutions for medical reasons can only be made up to 24 hours before the first match day.
Germany continues the European Championship with a match against Denmark on Tuesday, a few hours before Sweden meets Poland in Luzern.
