Borussia Dortmund have been hit with another set-back after learning their star striker Pierre-Emerick Aubameyang will be sidelined through injury.

Aubameyang has been in blistering form for the German giants this season and has scored seven goals in seven games - placing him second on the Bundesliga goalscoring chart.

But the pacey forward will now be spending time on the sidelines after the club revealed he has picked up a calf injury.

Despite the season still being in its infancy Dortmund have found themselves plagued by injury, with several big name players in the treatment room.

Manager Thomas Tuchel this week confirmed several of his star men, including Aubameyang, are out.

'(Christian) Pulisic, (Ousmane) Dembele and Aubameyang haven't trained today,' Tuchel told a press conference, report FourFourTwo.

Dortmund's growing injury list has been a concern for manager Thomas Tuchel

'Pulisic and Dembele are both ill and Aubameyang has a swelling in the calf muscles.

'And it will take several weeks, at least, for Marco Reus to return,' Tuchel added.

Dortmund are preparing for their upcoming DFB-Pokal Cup clash against second division side Union Berlin.

Tuchel will be hoping his side will be able to get a win over the Berlin men and reignite their faltering season.

Dortmund, with their much depleted squad, are yet to win a league game in October and have only picked up two points from their last three matches.

The injury crisis is even more untimely considering the Schwarzgelb's upcoming fixture schedule.

A local derby against rivals Schalke lies ahead at the weekend while a clash with Bayern Munich awaits Dortmund in mid November.
