The 27-year-old - who scored 12 goals as Die Schwarzgelben finished second in the Bundesliga last season - had been expected to make his first appearance of the campaign against the champions at the SIGNAL IDUNA PARK.
“He has a minor heel problem,” BVB coach Thomas Tuchel announced on Friday. “We do not want to take any risks following his long injury lay-off.”
Reus has yet to feature this season, with a pelvic injury keeping him sidelined until now. Dortmund can close the gap to champions Bayern to three points if they can win at home on Saturday and FCB coach Carlo Ancelotti is taking nothing for granted.
“That's tragic indeed,” said the Italian tactician of Reus’ predicament. “An injury is never nice. Reus is a fantastic player. But I think that Dortmund have the option to play other good players.”
