Ian Breckin is suspended for the FA Cup 2nd round game at the Deva Stadium and boss Gary Megson told the club website: "Danny Cullip will be captain assuming he's fit and available to play.
"He's no stranger to captaincy having done the job for Brighton and is a born leader."
Elsewhere on 2nd round day, former Forest favourites Nigel Clough and Brian Laws will be confident of making it to the next stage of the competition.
Clough's Burton Albion side, who knocked out Peterborough in round 1, face Burscough at home.
Laws takes his Scunthorpe side to Aldershot.
If Forest win or draw on Saturday (or if the game is postponed!) they will be number 64 in Sunday's 3rd round draw.
