Bayern Munich midfielder Thiago Alcantara is out of their Champions League tie with Manchester United.
The Spain international was taken off after 25 minutes of the 3-3 draw with Hoffenheim and taken to hospital where initial tests suggest a partial tear of the interior cruciate ligament.
"The first diagnosis for Thiago is a suspected partial tear of the ligament," Bayern said in a statement. "He will most likely miss both quarter-final legs against Manchester United."
Coach Pep Guardiola told reporters: "Thiago Alcantara will be out for about a month most likely. That is really bad news. We will miss him."
