Eintracht Frankfurt striker Ioannis Amanatidis is facing a lengthy spell on the sidelines after undergoing knee surgery.
The Greece international will spend the next few days in a local clinic, where he must rest the knee completely, before starting his comeback.
However, it will be several months at least before he can return.
The 27-year-old missed the whole of the second half of last season due to a problem with the same knee and the current injury is an after-effect of the operation he underwent last December.
