Middlesbrough midfielder Gary O'Neil has been struggling with a groin strain and is a doubt, and utility man Rhys Williams is suspended.
Andrew Taylor, Matthew Bates and Seb Hines are out with knee injuries, while Jeremie Aliadiere (ankle) and Caleb Folan (hamstring) are also sidelined.
MATCH PREVIEW Gordon Strachan and Mark Cooper both go into this game looking for their first win in their new jobs.
Strachan has presided over a draw and two defeats since taking over as Middlesbrough boss, while Cooper started his reign as Peterborough manager last weekend with a 1-0 defeat at Sheffield United and now faces his first home match in charge.
Defensive lapses have blighted Posh's season and Cooper's first signing is 6ft 7in central defender Exodus Geohaghon, who played under him at Kettering.
Geohaghon, a 24-year-old England C international who represented Great Britain at the World Student Games in the summer, was playing for Redditch in the Blue Square North just 18 months ago.
