Miles Addison could miss the rest of the season through injury, according to Derby boss Nigel Clough.
The versatile Addison suffered a foot injury during the Rams' 4-1 win over Blackpool and is currently waiting on tests to discover the full extent of the injury.
Clough fears Addison could be out for the rest of the current campaign.
"There's a possibility of that, or it could be a six-week job and we could get him back for the last month or so but we're not really sure," Clough told BBC Derby.
"The injury is not looking too favourable at the moment but until we get something confirmed we won't know for sure.
"But he is still in quite a bit of pain and it doesn't look too good."
