Matthew Spring returns to the Leyton Orient squad for the visit of Carlisle.
The midfielder has completed a three-match ban after his red card against Yeovil last month and could go straight back into the starting line-up.
But striker Alex Revell will miss the clash while defender Ben Chorley is an injury doubt.
Revell could struggle to play again this season after suffering knee ligament damage against Plymouth last week and Chorley has missed the last three matches with a thigh problem.
Jonathan Tehoue is likely to partner veteran Scott McGleish in attack while Elliot Omozusi will coninue at the back if Chorley is rueld out.
The Os are three points off the play-offs and have a game in hand on sixth-placed Bournemouth.
Carlisle manager Greg Abbott has no new injury or suspension problems.
The Cumbrians will play their fourth successive league game away from home - they have lost their previous three - but Abbott will be able to choose from an unchanged squad.
Striker Francois Zoko recovered from a calf injury sustained in the recent Johnstone's Paint Trophy final win over Brentford to play the full 90 minutes in Saturday's 3-2 defeat at MK Dons and is expected to continue.
On-loan Stoke winger Ben Marshall is likely to miss the rest of the season after sustaining ankle ligament damage against Brentford, so Liam Noble, on loan from Sunderland, should continue.
Striker Patrick Madden, defender Danny Livesey and Bermudan striker Nakhi Wells are all pushing for starts, while young forwards Ben McKenna and Ryan Bowman are hoping to retain their places on the bench again.
