Ghanaian forward Patrick Twumasi has injured his knee in training with the Bundesliga 2 side but it is not deemed serious.
Twumasi made the switch to the club from Spanish side Alaves in 2020 and has been played regularly.
He has scored two goals and given one assist in 11 league appearances so far.
His head coach was questioned about his injury and there was optimism.
"Thank goodness nothing broke," said Kenan Kocak.
"We are assuming an internal ligament stretch."
