Derby v Doncaster preview

Jamie Ward will return to the Derby squad for the visit of Donny.
The striker, on loan from Sheffield United, was ineligible against his parent club on Saturday as the Rams halted a nine-game winless league run at Bramall Lane.
Dean Leacock could also come back into the reckoning after a bout of illness. However, the central defensive partnership being formed between Shaun Barker and Daniel Ayala in his absence is likely to see him start on the bench.
Full-back Gareth Roberts missed out against Sheffield United through illness but could return to the fold.
On-loan goalkeeper Frank Fielding will make his second home debut for Derby after rejoining from Blackburn as Stephen Bywater (rib) and Saul Deeney (shoulder) remain sidelined.
Jake Buxton made his first appearance of the season as a late substitute at the weekend following groin, stomach and back problems and the defender could be included on the bench again.
Doncaster manager Sean O’Driscoll has the rare chance of naming an unchanged starting line-up for his side’s clash at Derby.
O’Driscoll, without 14 first-team squad members for last week’s draw at Norwich, was boosted by the return of leading goalscorer Billy Sharp in Saturday’s 1-1 stalemate with Watford, but there will be no other additions to the squad on Tuesday.
Goalkeeper Neil Sullivan, who suffered a recurrence of his shin injury and made way for Gary Woods against Watford, remains sidelined.
Midfielder Simon Gillett (knee) will start again on the bench, but defender Shelton Martis (ankle) is expected to miss out again.
Midfielders James Coppinger (calf), Martin Woods (groin) as well as Ryan Mason (leg) and striker James Hayter (calf) are still out, along with defenders James Chambers (hamstring), James O’Connor (foot) and Mustapha Dumbuya (knee).
