Dortmund's "Borussia" winger Jakub Blaszczykowski has once again suffered an injury and will have to miss a month of football due to a muscle strain.
The 28-year-old player has not played in official matches since January, when he tore his cruciate ligaments in a match against "Augsburg".
Blaszczykowski briefly returned to the lineup in pre-season matches against "Slask" before this injury, but now the Polish player will have to wait even longer before he can join the main team again.
"Unfortunately, it has been confirmed: Kubai has a muscle strain and he won't be able to play for about four weeks," said the footballer's official page on Facebook.
The list of injured Dortmund team players is getting longer. Recently, Marco Reus also joined the list, suffering a second ankle injury in four months during the European Championship qualifying match against Scotland.
"Borussia" is also missing Nuri Sahin (knee injury), Ji Dong-Won (Achilles tendon injury) and Ilkay Gundogan, who is still struggling with back problems.
