Ribery picked up the injury against Hertha Berlin on Sunday.
The news will come as a blow to Bayern, who are going through a tricky period at the moment.
Carlo Ancelotti was recently sacked as manager following the embarrassing defeat at PSG in the Champions League, and the draw at Hertha leaves them five points off the top of the Bundesliga table.
