BERLIN, Nov. 6 (Xinhua) -- Dortmund's Marco Reus will be sidelined for two weeks with torn muscle fibres, the "BVB" confirmed in an official statement.

Dortmund's worst fears came true as Reus will be ruled out for the "Revierderby" against rivals Schalke due to an adductor injury. The German international limped off the pitch at the halftime after Thursday's 4-0 victory over Gabala in Europa League.

It's a major setback for the BVB as Reus scored four goals in his last three Bundesliga appearances. According to Dortmund's statement, it is likely that Reus can make his comeback against Hamburg at the 13th round of Bundesliga.

The "BVB" sit currently at the second place with a five-point gap to front-runners Bayern Munich.
