Team news: Elliott Ward and Gonzalo Jara will go straight into Alex McLeish's squad as Forest prepare to face in form Peterborough.
Both defenders are likely to start, with skipper Danny Collins sitting out a one-match ban following his sending off against Oldham in the FA Cup.
Forest are also without Spanish defender Daniel Ayala, who is likely to be sidelined for three or four weeks with a hamstring problem.
A groin injury will keep Andy Reid out for a similar amount of time. Adlene Guedioura is with Algeria in the African Cup of Nations.
Karl Darlow will start in goal unless Forest sign another keeper, with Lee Camp having been told he is free to find another club.
PETERBOROUGH: SQUAD (FROM): Olejnik, Little, Alcock, Gordon-Hutton, Brisley, Bostwick, Rowe, Knight-Percival, Ajose, Swanson, McCann, Ferdinand, Newell, Boyd, Day, Clarke-Harris, Richens, Sage, Wootton, Petrucci.
Team news: Posh added to their squad by adding a face who will be familiar to both clubs to their ranks, in the form of Scott Wootton.
The defender has had loan spells at both Peterborough and Forest in the past, but has returned to London Road with his Manchester United team mate Davide Petrucci, on loan, for the rest of the season. Both men are expected to be involved tomorrow but Posh will be without Gabriel Zakuani, who is at the African Cup of Nations with Congo, and the suspended Lee Tomlin.
One to watch: George Boyd. The attacking midfielder or forward never quite demonstrated his potential during a loan spell with Forest, but he always seems to perform well when he plays against the Reds.
