Borussia Dortmund will be without Kevin Grosskreutz, Sebastian Kehl, Sven Bender and Erik Durm for the home game against 1. FSV Mainz 05 on Friday night, while Jakub Blaszczykowski is rated doubtful.

Durm has been down with fever, BVB coach Jürgen Klopp revealed on Wednesday, while Blaszczykowski is suffering from a sinus problem.” That’s why he wasn’t able to take part in training today. We have to wait and see how he recovers,” said Klopp.

Sven Bender and Sebastian Kehl have both returned to training, though they are restricted to individual work. The two Borussia Dortmund holding midfielders are expected to return to full training at the beginning of next week.

On Adrian Ramos, who was left out of the Freiburg squad, Klopp said: “It was not a decision against Adrian. I just decided that I only need one striker on the bench. It could be a whole different story on Friday.”
