Borussia MG forward Patrick Herrmann admits he is surprised by the extent of his knee injury after being ruled out for at least a month.
The club confirmed on Friday the 24-year-old had sustained a tear in the cruciate ligament in his left knee, but claimed that no surgery would be required.
The Germany international is set to miss at least a month while he rehabilitates the injury, but admitted that the seriousness of the problem came as a surprise.
"That was obviously a bit of a shock," Herrmann told German publication Bild.
"I did have discomfort but I'm not the type of guy who runs to the doctor over every little thing. We used the international break to do a check-up and this came to light."
Club doctor Stefan Hertl confirmed Herrmann would undergo treatment over the next month before the situation would be reassessed.
"After speaking to some specialists, we have decided against an operation," he added.
"Patrick will undergo conservative treatment and try to make steady progress after the coming four weeks. After that the club and player will decide what happens next."
