Leyton Orient will check on skipper Stephen Dawson.
Dawson has been struggling with a back injury recently and came off at half-time during last weekend's 2-1 defeat at Exeter, but the Os' key midfielder is hoping to be fit.
Defender Ben Chorley remains a doubt with the thigh injury which has sidelined him since last month, midfielder Jimmy Smith could miss out again with a knee problem and winger Paul-Jose Mpoku is struggling with an ankle knock.
Striker Alex Revell will miss the clash and is unlikely to play again this season due to knee ligament damage.
Russell Slade's side are five points adrift of the play-off places with four games remaining.
Peterborough manager Darren Ferguson is waiting on the fitness of Tommy Rowe before naming his squad.
The winger was replaced at half-time of the 2-1 win over Plymouth last weekend with a groin strain and could miss out. Forward Lee Tomlin replaced him against Argyle and could return to the starting line-up.
Defender Mark Little is fit after an ankle problem sustained in training but Grant Basey is out.
Basey is likely to be out for a couple of weeks with a knee injury picked up at Huddersfield while fellow left-back Tom Kennedy only has a slight chance of involvement in the play-offs after damaging his knee ligaments in the recent win at Dagenham.
Midfielder Lee Frecklington (hernia) is back after being sidelined since October but striker Dave Hibbert is absent as he steps up his comeback from a dislocated knee suffered in November.
