Borussia Dortmund captain Marco Reus has suffered a fresh injury blow which will keep him sidelined for the foreseeable future.
"Reus has worked hard and made progress in recent months, but he still has problems with certain movements," said a statement on BVB's official website. "A conservative therapeutic approach is being used to treat the injury."
Before sustaining that groin injury at the start of the year, Reus had been enjoying a superb run of form with his hometown club, contributing 11 goals and five assists to their title chase. After his last league outing - a 5-0 thrashing of Union Berlin on Matchday 20 – BVB sat just three points off top spot, but ultimately ended up 13 adrift of champions Bayern Munich.

Reus had returned to team training in early June but was still working his way back to full fitness. This latest setback means he could potentially miss the first competitive outing of 2020/21, Dortmund's trip to MSV Duisburg in the DFB Cup first round in mid-September.
The attacking midfielder has not been spared by injuries down the years, with an ankle injury costing him a place in Germany's 2014 FIFA World Cup-winning squad. The 44-time international also missed much of 2017/18 due to a cruciate ligament rupture.
