Posh host league leaders Cardiff City at London Road on Saturday (3pm).
Peterborough United host league leaders Cardiff City at London Road on Saturday afternoon in a vital npower Championship encounter (3pm).
Darren Ferguson's men know that three points will take them out of the drop zone as Sheffield Wednesday face Barnsley this weekend.
'Our home form hasn't been anywhere near we would like, but we have the chance to change that at the business end of the season. Cardiff will be a difficult game, but we have proved we can beat them this season. The lads have watched the DVD back and we know what is required,' Ferguson said.
Ferguson has described Michael Bostwick's chances of being fit as 50-50, but Tommy Rowe will definitely be fit after recovering from a knock. Alex Pritchard is unavailable, while Davide Petrucci has returned to Manchester United after failing to recover from a hamstring injury.
New loan signing Florent Cuvelier will be in the squad after joining from Stoke City. Peter Grant is a long term absentee with injury.
Cardiff City away form is impressive, tasting just one defeat in their last six, and picking up four good wins. The games have constituted a decent return of eight goals for the Bluebirds, and five goals against.
Cardiff have sold over 2,000 tickets in advance for the game so a big crowd at London Road is expected. Tickets are still available and can be purchased at www.theposhtickets.com, via the 24-hour hotline 0844 847 1934 or at the Box Office, which is open on Good Friday.
