Borussia Dortmund will reportedly have to manage without at least two of their key players against Hertha BSC tomorrow.
According to Ruhr Nachrichten, first-choice goalkeeper Gregor Kobel and experienced centre-back Mats Hummels haven't traveled to Berlin.
Marwin Hitz is in line to replace Kobel while Emre Can could fill in for Hummels in central defence.
Ruhr Nachrichten further reports that Raphael Guerreiro and Marius Wolf have been deemed fit enough to be part of the squad.
