With 24 hours to go until the Bundesliga clash with Eintracht Frankfurt, Peter Bosz still doesn't know who will line up at the back. The coach has a number of injury concerns to contend with ahead of the trip.

In addition to André Schürrle, Marco Reus and Sebastian Rode, who all play in midfield positions, Bosz is without four defensive specialists in Sokratis (one-match suspension), Lukasz Piszczek, Raphael Guerreiro and Erik Durm. There are also question marks surrounding the involvement of Ömer Toprak, who was substituted off with a thigh strain in the Champions League clash with Nicosia in midweek, and captain Marcel Schmelzer, who only made his comeback on Tuesday following two five-week spells on the sidelines with injury.

Bosz did not want to comment on whether the left-back, who has hardly been able to train with the team yet, is in contention to make another appearance four days later. "I will discuss it with the doctor and then I'll know what the situation is with the players," he said. (br)
