Easton may miss out after sustaining a calf problem in training ahead of last weekend's 3-0 defeat against Bristol Rovers.
But defender Callum Kennedy (pelvis) is definitely ruled out of the clash against Gus Poyet's side.
Striker Lloyd Macklin returned from a leg fracture to make a successful comeback in that clash and is likely to again be named among the substitutes. Winger Alan O'Brien is now regularly involved in the first-team squad again after a hamstring injury.
Midfielder Kurt Hammonds (knee) is set to return to training in the near future while fellow long-term absentee Hasney Aljofree (knee) continues to build up his fitness with regular games in the reserves.
