Goetze suffers hamstring tear
The 19-year-old suffered the injury in yesterday's 1-1 home draw with Kaiserslautern after coming off the bench to play the last 25 minutes. After a scan on Monday, Borussia's team doctor Markus Braun confirmed the news.
Goetze will sit out Dortmund's league game at bottom side Freiburg on Saturday and the third-round German Cup match against second division Fortuna Duesseldorf on 20 December with a place in the quarter-finals at stake.
Goetze had injured his groin in last week's UEFA Champions League defeat by Marseille before his brief appearance against Kaiserslautern.
