Cambridge midfielder Gary Deegan could retain his place in the side for the visit of Crewe.
Deegan returned to the starting XI following a broken foot for the 1-0 win over Barnet on Boxing Day.
Fit-again midfielder David Amoo could also be in contention having come off the bench for the second half.
Jabo Ibehre has also been working his way back to full match fitness, while fellow forward Harrison Dunk continues to be assessed on a knee problem.
Crewe boss David Artell may be tempted to name an unchanged side following the Boxing Day win against Chesterfield.
Artell made three changes for the trip to the Proact Stadium after a 3-0 home defeat to Swindon, recalling Charlie Kirk, Chris Porter - both of whom scored - and Conor Grant.
Should Artell opt to change things again, Harry Pickering, George Cooper and Jordan Bowery are among those hoping to get back into the team having been the players replaced in midweek.
George Ray (back), James Jones (pelvis) and Ryan Wintle (fractured tibia) have been long-term absentees but are back running again, although the trio will not be available again for a few weeks.
