Peterborough may hand a debut to Exodus Geohaghon when Middlesbrough visit London Road.
The 6ft 7ins centre-half followed manager Mark Cooper from Kettering this week and may be given the chance to showcase his huge throw against Gordon Strachan's side.
Cooper was pleased with his side's display in the 1-0 defeat at Sheffield United last weekend and may keep faith with the XI who started at Bramall Lane as he has no injury concerns.
Russell Martin has joined Norwich on loan so Charlie Lee will continue at right-back while forward George Boyd will continue to don the captain's armband.
Posh have not won since beating Scunthorpe a month ago but three points against misfiring Boro could see them move off the bottom of the Championship.
New Middlesbrough skipper Gary O'Neil is a doubt for the trip.
The 26-year-old has been struggling with a groin strain but manager Gordon Strachan is hopeful he will be available after appointing him as his captain in place of defender David Wheater.
Utility-man Rhys Williams, who was used at right-back in last weekend's 1-1 draw with Nottingham Forest, is suspended after reaching five bookings for the season.
Central defender Chris Riggott is closing in on a senior return after recovering from a second bout of ankle surgery.
However, Jeremie Aliadiere (ankle), Seb Hines (knee), Caleb Folan (hamstring), Andrew Taylor (ankle ligaments) and Matthew Bates (cruciate ligament) remain on the sidelines.
