Derby boss Nigel Clough is considering giving Jeff Hendrick a breather against Birmingham.
The 20-year-old has started all but one of the Rams' 17 npower Championship games but has struggled to reproduce the level of performance he showed last season when he won the club's Young Player of the Year award.
``We either persevere with him or there is a chance he might come out and have a little rest. At 20, we could possibly do more damage leaving him in there,'' said Clough. ``He had a great first season but he is struggling a bit this season. Second seasons are tough for young players like Jeff because everyone knows a bit more about you.''
Clough is set to revert back to 4-4-2 for Saturday evening's televised clash, having lined up 4-4-1-1 in the 3-0 defeat to Crystal Palace last weekend.
If Hendrick drops out, Will Hughes and Craig Bryson would be the likely partnership in central midfield with Paul Coutts on the right and Michael Jacobs could keep his place on the left after a lively display at Selhurst Park.
Clough had hoped Jamie Ward would be available after missing nine matches with a hamstring injury but the forward is likely to be overlooked unless he joins in training with the rest of the squad before the end of the week.
Curtis Davies is back in contention to boost Birmingham ahead of the trip while loan signing Robert Hall could make his debut.
Influential centre-back Davies has missed City's last two matches with a niggling ankle injury but is back in the frame to face the Rams at Pride Park, kick-off 5.20pm.
Promising winger Hall, meanwhile, arrived on loan from West Ham late on Thursday afternoon and goes straight into contention for his Blues bow.
There is further positive news regarding on-loan right-back Paul Caddis, who returned to full training on Friday having been sidelined for two months with his shoulder injury. However, Saturday's game is expected to come too soon.
Left-back David Murphy underwent a knee operation on Thursday night which rules him out for the foreseeable future, joining fellow defender Stephen Carr (knee) on the sidelines.
Midfielder Keith Fahey is expected to remain unavailable having been granted compassionate leave for an indefinite period.
