Peterborough manager Darren Ferguson will be without left-back Jamie Day for the visit of Nottingham Forest.
Day returned from an ankle injury to make his first start since September 2008 against Plymouth on Tuesday night but was replaced in the second half with a foot injury.
He has had five stitches in a deep gash on his foot and will miss out so Tommy Williams will come back into the side.
Utility-man Charlie Lee made a surprise return at the heart of defence in midweek after an ankle problem but also came off after complaining of tight calves.
He is a doubt and Gabriel Zakuani is on standby to return after being dropped from the squad altogether.
Midfielder Paul Coutts is also hoping to return as Ferguson looks for a much-needed second win of the season.
Nottingham Forest are aiming for a hat-trick of Championship victories for the first time under Billy Davies.
Davies reported no fresh injury concerns following the midweek win over Scunthorpe which lifted the East Midlands club to within three points of a play-off spot.
Defender Kelvin Wilson, who made his first league start of the campaign at Plymouth on Sunday, was rested against the Iron after suffering a severe bout of cramp in Devon.
He should return to the squad but it remains to be seen whether he will go straight back into the starting line-up after his replacement Luke Chambers, who scored Forest's first goal against Scunthorpe, produced a solid performance on Wednesday night.
Davies could continue to rotate his striking options with Robert Earnshaw and David McGoldrick pushing for places.
