Hannover 96 attacker Patrick Twumasi will be out for sometime after sustaining an injury.
Twumasi, who was replaced in the 57th minute in the derby on Saturday, has now been diagnosed.
An in-depth investigation has shown that the forward has torn a fiber tear on his back thigh muscles.
“He will be out for the next two to three weeks,” said 96 head coach Kenan Kocak after the session early Tuesday afternoon.
The Ghana international is having a decent season for his side having scored four goals for the Club so far.
