Mats Hummels will miss three weeks after picking up an injured right foot during Borussia Dortmund's 2-1 loss at Bayern Munich on Saturday.
Hummels went off at halftime and his replacement, Neven Subotic, was at the center of allowing Bayern's two second half goals.
Dortmund currently is 16th with just seven points from 10 matches in the Bundesliga.
