Anderson set to miss for Derby
Derby defender Russell Anderson is set for a short spell on the sidelines with a hamstring injury and will miss the visit of Watford.
The experienced centre-half, who has only recently returned to first-team contention after two months out with a groin problem, suffered the injury playing for the reserves this week.
It is hoped this absence will only be a short one and Anderson could resume training within the next 10 days.
Midfielder Stephen Pearson has returned to training after missing the last three matches with a knee injury and could be included in the squad.
Luke Moore has extended his loan spell from West Brom and could be restored to the starting line-up.
However, fellow forward Ryan Noble has returned to Sunderland following his month-long stay at Pride Park.M
