The Rams are expected to play a vastly changed team to the one which beat Bolton in the Championship at the weekend.
Derby County are expected to play players in the squad who missed out on selection for the away win over Bolton Wanderers at the weekend.
Tonight's game will be the replay for the abandoned match at Grimsby two weeks ago which saw several inches of rain drop throught a very soggy day for fans and players alike.
The Rams will look to play a strong side, with Gary Rowett having the luxury of playing players like Chris Martin and Mason Bennett who didn't feature in the starting eleven at the weekend.
Midfielders such as Akechi Anya and Jamie Hanson may also get a game. Scot Carson is also expected to be rested in favour of Jonathan Mitchell in goal.
Should Derby progress in tonights 2nd round replay they will not have wait only until Thursday to find out who they will play in round three of the competition. Bazarrely the draw is to take place in Beijing of all places at 11.15 local time, which is at a very early 4.15 BST !
Tonight's referee for the reply will be the original official, Trevor Kettle, hopefully fans will not have had a wasted journey for tonight's game as the weather is predicted to be mostly sunny up till kick-off with just a chance of showers around 11.00pm
