Colchester will check on Kayode Odejayi and Franck Queudrue ahead of the visit of Swindon.
Striker Odejayi was ruled out of the Easter weekend matches with a foot injury and defender Queudrue suffered a hamstring strain during Monday's defeat by Millwall.
Queudrue has undergone a scan and is rated a major doubt so Danny Batth and Matt Heath are on standby to deputise at centre-half.
The Us are without a win in eight games and have slipped out of the play-off places so boss Aidy Boothroyd could make changes.
David Fox, John-Joe O'Toole, Ian Henderson and Steven Gillespie are all pushing for recalls.
Winger Simon Hackney has extended his loan spell with Morecambe until the end of the season.
Vincent Pericard will be available for Swindon as Danny Wilson looks to maintain the club`s grip on second place.
The striker trained on Thursday having overcome a niggling hamstring problem and returns to the frame, although he will struggle to dislodge the first-choice pairing of Charlie Austin and Billy Paynter and will have to settle for a place on the bench.
Alan Sheehan came back in for Monday`s 3-0 win over Tranmere having been ineligible for last weekend`s stunning victory at parent club Leeds, and he should again start at full-back in what is likely to be an unchanged XI.
Callum Kennedy (pelvis) played an hour for the reserves after his lengthy absence and could still return this season, but Kurt Hammonds (knee) and Alan O`Brien (hamstring) remain unavailable.
Young right-back Nathan Thompson has also suffered a hip flexor injury but will be back in training next week.
