Sint-Truidense forward Elton-Ofoi Acolatse suffered an injury during training on Thursday.
The 22-year-old Ghanaian-born Dutchman sustained a fracture in the metacarpal bone and could be out for a long period.
Acolatse is on loan from Club Brugge.
He has been key for Sint-Truidense since the start of the season.
However, it's unclear if he will return to his parent club to continue his rehabilitation.
He is still contracted to the side until 2021.
