Borussia Dortmund are set to face Tottenham in the Champions League on Wednesday without captain Marco Reus, who suffered a muscle injury last week.
Speaking on Sunday, Dortmund sporting director Michael Zorc told Ruhr Nachrichten: “I think we’ll decide that at short notice, but I don’t expect a miracle healing.”
Dortmund could also be without vice-captain Lukasz Piszczek, who picked up a knock in the 5-1 win over Hannover earlier this month.
Although the right-back played in the 3-3 draw with Hoffenheim at the weekend, Ruhr Nachrichten reported that he could miss the trip to Wembley.
However, defender Dan-Axel Zagadou took a major step towards a comeback from injury after playing 60 minutes for the reserves at the weekend.
The draw with Hoffenheim means Dortmund have gone three games without a win for the first time this season, and have conceded six goals in their last two games.
