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.

Nmecha suffered damage to his knee ligaments after a challenge and was subbed out 12 minutes into Saturday’s 2-2 home draw with Werder Bremen.

According to Bild, Dortmund will react to the injury by recalling Salih Özcan from his loan spell at VfL Wolfsburg to provide cover in defensive midfield. All parties are said to have agreed to cut the loan short, with only the signatures missing.
