Cambridge have a host of injury concerns for the home game against Crewe.
Brad Halliday and Rushian Hepburn-Murphy were nursing minor problems at the weekend but both played in the 1-1 draw with Oldham.
Jake Doyle-Haynes (ankle), David Forde (shoulder) and Kevin Pilkington (wrist) have all been out recently but are nearing returns. It remains to be seen if Tuesday night’s match comes too soon for them to be involved.
One player who definitely will not be available to boss Colin Calderwood is Liam O’Neill after he suffered a setback in his recovery from a hip problem.
Crewe boss David Artell has no new problems as he looks to snap a three-match losing run.
James Jones made his return from a six-game absence with ankle ligament damage to play the full 90 minutes at Tranmere on Friday, although Artell may manage the midfielder’s comeback by using him as a substitute at the Abbey Stadium.
Nicky Hunt and Aaron Taylor-Sinclair have missed the last two games and Artell will make a check on their fitness.
Taylor-Sinclair has returned to training after a slight knock and he is the more likely of the two to be back in contention.
