The Germany international will be absent for the last eight of the competition but hopes to return in time to play in the DFB-Pokal semi-final against Wolfsburg
Borussia Dortmund have confirmed that defender Marcel Schmelzer will be missing for up to a month with a groin injury, ruling him out of the Champions League quarter-finals.
The left-back sustained the injury in Dortmund's 2-1 defeat to Zenit in the last 16 on Wednesday, with BVB qualifying for the quarter-finals 5-4 on aggregate.
It is the second time this season that BVB have been without Schmelzer after the 26-year-old missed three weeks of action prior to Christmas with a calf strain.
This latest setback means the star is likely to miss games against Hannover, Schalke, VFB Stuttgart, Wolfsburg and Bayern Munich as well as the quarter-finals of Europe's premier club competition.
A statement on Dortmund's website said the Germany international is targeting a return for their DFB-Pokal semi-final clash with Wolfsburg on April 15.
