Derby County will be hoping to avoid an upset when they host Chesterfield in the fourth round of the FA Cup this weekend.
The in-form Championship side needed a late goal to edge out Southport in the third round, but Chris Martin's injury-time penalty ensured that Steve McClaren's side did not need a replay.
The Rams come into this match on the back of a defeat though, having been beaten 2-1 by Nottingham Forest in the league at the weekend, costing them the chance to move to the top of the Championship.
Will Hughes picked up a knock during Saturday's defeat, but is expected to be available for the Cup match, despite being substituted at half time at the weekend.
New signings Stephen Warnock and Raul Albentosa have been training with the club this week, but Derby are still awaiting international clearance in order for the latter to feature.
Meanwhile, Chesterfield are in the fourth round for the first time since reaching the semi-final in 1997 after knocking out Scunthorpe in the third round.
The League One side's cup run coincides with a solid run in the league, with three wins in their last five outings, and just the one defeat, leaving them eighth in the table.
Romuald Boco featured in the last round, but he left the club to join Bharat FC in India earlier this week after turning down the offer of a new contract with the Spireites.
On-loan Sheffield Wednesday striker Mani Dieseruvwe could take his place in the side after featuring off the bench in the defeat to Swindon Town last weekend.
This will be the first competitive meeting between these two sides since 1986, when Chesterfield came out on top with a 1-0 win.
