Derby defenders Dean Leacock and Dean Moxey are suspended for the visit of Ipswich.
Leacock begins a two-match ban after he collected his 10th yellow card of the season in the home defeat to East Midlands rivals Nottingham Forest. Moxey was sent off in that game and misses out with a one-match ban.
With Russell Anderson (calf) and Jake Buxton (back and groin) still out, boss Nigel Clough tried to ease his defensive problems with the loan signing of Liverpool's Daniel Ayala.
However, the Spaniard is on his way back from a hamstring injury so it has been decided that he will continue his rehabilitation at the Premier League club and link up with Derby later next month.
Miles Addison and Shaun Barker are likely to form the central defensive partnership, while Gareth Roberts is expected to return at left-back in place of Moxey.
Steve Davies could make his first start of the season if Clough fails to sign a forward to replace Kris Commons, who has joined Celtic. Midfielders James Bailey, Paul Green, Stephen Pearson and Tomasz Cywka are also available for recalls.
Jimmy Bullard could make his Ipswich debut against Derby on Tuesday night.
The 32-year-old joined on loan from Hull last week and is fully fit after recovering from the knee injuries which have dogged the last few years of his career.
He could be handed an instant start in the centre of midfield although Mark Kennedy, Colin Healy and captain David Norris all impressed against Arsenal last time out.
Fellow new signing Andy Drury could also feature after he signed from Luton on deadline day with the winger set for a place on the bench.
Lee Martin is available again after being cup-tied for the Carling Cup defeat at the Emirates, but goalkeeper Brian Murphy is set to be out for at least three months with an ankle injury and winger Shane O'Connor remains sidelined with a dislocated shoulder.
