The American midfielder should be ready for action after the international break, with the Norwegian striker also nursing an injury at present
Borussia Dortmund coach Marco Rose has ruled Giovanni Reyna and Erling Haaland out of his immediate plans, but the hope is that both will be ready to resume domestic action after the international break.
United States international playmaker Reyna has been sidelined since picking up a hamstring problem while away with his country in September.
He will not be rushed back for a Bundesliga clash with Augsburg on Saturday, with Rose looking for the talented 18-year-old to make a meeting with Mainz on October 16.
