The winger has not featured for Edin Terzic's side since March 2 when he picked up a thigh injury, which made him unavailable for last month's England World Cup qualifiers and Dortmund's first-leg tie against Sancho's former club.
Sancho has been in impressive form this season, scoring 12 goals and registering 16 assists for the German club, despite Dortmund struggling in the Bundesliga, currently sitting in fifth.
The Daily Mail reports that the 21-year-old completed an individual session on Sunday, after warm-weather recuperation in Dubai.
Sancho left Man City for Germany in 2017, and has gone on to score 46 goals and provide 60 assists in 130 appearances for his current club. body check tags ::
