Adam Collin is close to returning to the Notts County first team but will not be ready to face Cambridge.
Goalkeeper Collin has not featured since mid-October with a knee problem but is finally back in full training and building match fitness.
Club captain Michael O'Connor remains a long-term absentee having suffered a major knee injury in April.
Jonathan Forte, Lewis Alessandra and Rob Milsom all stand by in hope of recalls.
Cambridge boss Shaun Derry goes to his former club with his future on the line and he could make changes, with striker Uche Ikpeazu available following a one-match suspension.
Last Saturday's last-gasp loss to Newport means United have just one win in eight games, while they are the lowest scoring side in the division and Derry has only been assured of his position for the Christmas period.
Ade Azeez played 90 minutes on his first start following three months out with a calf injury.
Derry named just four substitutes against Newport and could be short of options, with Gary Deegan (foot) and David Amoo (undisclosed) expected to miss out again.
