Elliot went off at half-time in Saturday's 1-1 draw with Tranmere due to a hip injury and is unlikely to be fit.
If he fails to make it, Ross Worner could be set for a starting berth.
Centre-back Gary Doherty is unlikely to return after he missed out at the weekend with a hamstring injury so Miguel Angel Llera will continue in his place.
On-loan West Ham left-back Matt Fry (knee), midfielder Johnnie Jackson (Achilles) and striker Joe Anyinsah (ankle) remain doubts.
Striker Paul Benson made his first start since January 3 on Saturday after recovering from a hamstring problem and should keep his place.
