Borussia Dortmund midfielder Felix Nmecha will be out for a few weeks after sustaining a knee injury, interim manager Mike Tullberg said ahead of Wednesday's Champions League home clash against Ukrainian side Shakhtar Donetsk.

Borussia Dortmund will have to be without Felix Nmecha for "a few weeks" after the Germany midfielder injured knee ligaments, interim coach Mike Tullberg confirmed Tuesday. Nmecha went down after a challenge and was subbed out 12 minutes into Saturday's 2-2 home draw with Werder Bremen.

Borussia Dortmund hope to bounce back from last week's Bologna defeat as they face Shakhtar Donetsk under interim boss Mike Tullberg.
