It was initially hoped that the 25-year-old would return to fitness for Dortmund's preseason training, but further tests confirmed that the Germany international would be out of action for three months and would subsequently miss the start of the 2014-15 Bundesliga season.
Dortmund sporting director Michael Zorc has now revealed that, barring setbacks, Reus' recovery is on track, meaning he could feature for Germany in its internationals against Argentina on September 3 and Scotland four days later.
"It [his recovery] is going well", Zorc told Germany magazine, Kicker. "We have to see how he withstands the pressure [on his foot]."
Reus won the German players' player of the year award for his Bundesliga performances last term, and scored 23 goals in 44 appearances in all competitions for Dortmund.
