Marco Reus limped out of Borussia Dortmund's DFB-Pokal tie on Tuesday to prompt further concerns over the Germany international's fitness.
Borussia Dortmund face an anxious wait to see if Marco Reus is set for another lengthy stint on the sidelines after he limped out of Tuesday's DFB-Pokal clash with Dynamo Dresden.
Reus, who signed a new long-term contract with Dortmund last month, had to be helped from the field in the first half of the last-16 tie due to an apparent injury to his left knee.
The 25-year-old has been plagued by injuries in recent times and was forced to miss Germany's 2014 World Cup success after tearing ligaments in his left ankle.
He subsequently suffered similar problems in September and November last year, leading to further lay-offs.
Following Reus' latest setback, the German Football Association (DFB) tweeted a 'get well soon' message to the forward.comments
