Borussia Dortmund midfielder Marco Reus was dropped from Germany’s European Championship squad on Tuesday, and captain Bastian Schweinsteiger made the final cut despite injury, the Associated Press reports.

Reus, who had been struggling at the team’s training camp in Ascona, Switzerland, was omitted from the final list of 23 players, along with Hoffenheim defender Sebastian Rudy and Bayer Leverkusen players Julian Brandt and Karim Bellarabi.

“The doctors could not give a clear prognosis,” Germany coach Joachim Loew said of Reus. “He has huge health problems and can only walk straight at the moment. More wasn’t possible in training so far.”

Loew said there were too many doubts over whether Reus could recover in time for the tournament in France.

“It’s a bitter decision for us and for him, a disappointment for us all, because a Marco Reus in form, healthy and fit, would have been a huge addition,” Loew said. “But for technical reasons we have to take this decision as we know this tournament will be very strenuous.”

Reus also missed Germany’s World Cup win in 2014 because of injury in a friendly match against Armenia.
