Borussia Dortmund will be without forwards Karim Adeyemi and Julien Duranville for several weeks after they both picked up injuries in Tuesday's 7-1 victory over Celtic in the Champions League, coach Nuri Sahin said on Friday. The Ruhr valley club earned their highest European win, with Germany international Adeyemi scoring a hat-trick before taken off with a muscle injury and replaced by 18-year-old Belgium international Duranville, who also suffered an injury in that game.
