Wolves striker Sasa Kalajdzic has suffered an ACL injury while on-loan with Eintracht Frankfurt.
It's the second serious knee injury the Austrian has had in 18 months.
Kalajdzic joined Eintracht Frankfurt in the January transfer window and had registered one assist in five games.
He signed with Wolves for 15m in 2022 from VfB Stuttgart but missed last season after he suffered a knee injury on debut.
