Borussia Dortmund will be without the services of Marco Reus for the next fortnight.
The German international was replaced in the 65th minute of Dortmund's 5-1 victory over Werder Bremen yesterday afternoon.
After a scan, it has been confirmed that the 24-year-old has suffered a muscle tear that will keep him sidelined until the end of the month.
As a result, he will now miss encounters against Eintracht Frankfurt and Hamburg.
Dortmund have also revealed that midfielder Sven Bender suffered a thigh strain in the same match and will be out of action for around seven days.
