Derby hope to extend Fredrik Stoor's loan spell from Fulham this week.
The right-back's initial month-long stay at Pride Park expired after Saturday's 4-2 home defeat by QPR, during which Stoor had to be substituted due to a black eye.
"His eye completely closed. If you have seen the Rocky films, you'll know what I mean," said Clough. "He has a good black eye and there was no way he could continue but we are looking to extend his loan."
