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.
