Ellison, on loan from Rotherham, has missed the last six games due to a thigh injury but could be included in the squad.
Midfielder Tom Adeyemi is unavailable though. The 19-year-old missed the midweek draw with Burton because of a similar problem and has returned to parent club Norwich for treatment.
Manager Peter Jackson made five changes for Tuesday night's 1-1 draw, with winger Omar Daley, defender Steve Williams, striker James Hanson and goalkeeper Lenny Pidgeley among those hoping to retain their places in the starting line-up.
Another, defender Lewis Hunt, was handed a surprise recall against Burton after being told it was unlikely he would play again this season due to contractual reasons and he should continue.
Striker Jake Speight is hoping for a recall after stepping off the bench to fire the equaliser in midweek.
