Borussia Dortmund will be without starlet Mario Gotze until after the winter break due to a thigh injury.
The 19-year-old playmaker sustained the knock in Sunday's 1-1 Bundesliga draw with Kaiserslautern.
The strain will force him to miss Saturday's game against Freiburg and next week's German Cup clash with Fortuna Dusseldorf.
Gotze has scored five league goals in Germany's top flight this season, missing just two of their league games.
Second-placed Dortmund have drawn their last two league games to drop three points behind leaders Bayern Munich.
