Dortmund's "Borussia" duo Pierre-Emerick Aubameyang and Lukasz Piszczek have left their national team camps due to injuries and have joined the club.
Gabonese striker Aubameyang suffered an injury in the 4-0 qualifier match for the African Nations Cup against Sudan, so he will miss a friendly match against Zambia.
However, the 26-year-old footballer tweeted that his injury is not serious and he may be able to appear in the Bundesliga match against Hannover on Saturday.
Meanwhile, Poland's national team defender Piszczek injured his ankle in the lost match against Germany and will undergo tests. However, it is expected that doctors will allow the 30-year-old to wear the BvB jersey in the weekend.
Piszczek will have to watch the Polish match against Gibraltar on television today.
