The eight-goal striker, United's leading scorer this season, has missed the last six games with a knee injury but returned to full training on Thursday and, should he suffer no ill-effects, will be back in the fold to face the O's.
Left-back Bradley Garmston overcame a knee injury sustained on Good Friday to take his place on the bench for Monday's 1-1 draw at Oldham and he will be pushing for a starting berth this time around.
George Porter serves the final game of his three-match suspension while defender Tom Eastman is also expected to miss out once more due to injury.
The U's remain just three points above the relegation zone with five games to go.
