In Sunday's match against "Freiburg", Dortmund will have to play without the injured striker Lucas Barrios.
The footballer, who has scored 13 goals this season, got injured in the weekend's match against "Hamburg", which ended in a 1-1 draw.
It is expected that Barrios will be ready for the next match against Borussia Monchengladbach.
Currently, Dortmund is leading the national championship, but is only five points ahead of Leverkusen's Bayer in second place.
