Stanley duo return
Accrington can welcome back loanees John O'Sullivan and Sean Maguire against Cambridge.
Blackburn midfielder O'Sullivan and West Ham forward Maguire were ineligible for the FA Cup first-round replay win over Notts County in midweek.
Stanley could hand a debut to new signing Matt Crooks, who signed on loan from Huddersfield on Thursday.
Midfielder Anthony Barry (knee) is back in training, while defender Adam Buxton (thigh) is making progress.
Midfielder Matty Blair could make his debut for Cambridge after joining on loan from Fleetwood this week.
Defender Michael Nelson should also be available after missing last week's 2-1 win over Northampton due to compassionate leave.
However, Harrison Dunk is facing up to two months out of action following a hernia operation and Ian Miller is still not ready for a seasonal reappearance.
Ryan Donaldson and Tom Elliott also remain sidelined due to knee problems and are not expected to be fit in the near future.
