That means United States international Reyna now has the opportunity for more playing time at Dortmund as they look to end Bayern Munich's 10-season stranglehold on the Bundesliga title.
Last season the 18-year-old became an important player for Dortmund alongside Erling Haaland as the club qualified for the Champions League and won the German Cup.
In 23 Bundesliga appearances, Reyna scored four goals and set up five more.
Players to have previously worn the No. 7 for Dortmund include Ousmane Dembele, Shinji Kagawa, Robert Lewandowski, Patrik Berger, Steffen Freund, Andreas Moller, Thomas Helmer and Michael Zorc.
