Marco Reus is out of Borussia Dortmund's Champions League clash with Arsenal.
Reus is out of Arsenal's Champions League visit to the Westfalenstadion after partially tearing his ankle ligaments against Scotland.
The Germany star has been ruled out for four weeks after a tackle by Charlie Mulgrew left him on the floor.
Arsenal travel to Germany on September 16 to face Dortmund in the Champions League group stage - the third time in four years that the clubs have been drawn together - and Reus will not return until early October at the earliest.
