Os wait on Dawson
Leyton Orient will check on skipper Stephen Dawson ahead of the visit of Peterborough.
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.
