Aberdeen have confirmed Ryan Edmondson could be out for up to four months after suffering an ankle injury in training.
A scan revealed the on-loan striker will miss three to four months, and the 19-year-old has now returned to parent club Leeds to see a specialist.

Aberdeen only signed Edmondson on loan a fortnight ago after Sam Cosgrove sustained a knee injury which could keep him out for four months.
The length of Edmondson's own injury, and return to Leeds for further assessment, means he may not return to action before his loan deal expires in January.
Edmondson has only made one appearance for Aberdeen so far, coming off the bench in the 1-0 loss to Rangers on the opening day of the Premiership season.
Aberdeen have since had their subsequent three matches postponed after eight players broke coronavirus rules by visiting a bar.
