Van der Vaart said that he has started to train at full capacity following his injury, which should see him get straight back into the squad for Saturday.
"I feel good," Bundesliga.com quotes him as saying. "The training game was important and went well, and I'll be training with the team as normal again.
"If everything progresses smoothly, hopefully I'll play at the weekend."
Van der Vaart picked up his injury on international duty with the Netherlands.
