Gus Poyet's side were denied three points in a controversial affair with Leeds on Friday night and have not won in front of their own fans since the middle of September when they beat Sheffield Wednesday, who downed opponents Peterborough at the weekend.
The Posh, who haven't drawn a game all season, have won two of their last three matches away from London Road and could climb out of the bottom three with a victory on the south coast.
Possible starting lineups:
Brighton: Kuszczak; Bruno, Greer, El-Abd, Bridge; Bridcutt, Hammond, Orlandi; Buckley, Mackail-Smith, Barnes
Posh: Olejnik, Alcock, Brisley, Bostwick, Tomlin, Boyd, McCann, Little, Knight-Percival, Ntlhe, Berahino
Sports Mole says: 2-0
