Coventry left-back Blair Adams extended his loan stay from Sunderland on Tuesday and is therefore available, along with fellow loanee James Bailey.
The pair both started City's quarter-final success over Sheffield United.
Striker Leon Clarke did not play in the competition during his loan spell with Scunthorpe over the first half of the season and is therefore not cup-tied.
Manager Mark Robins is also unlikely to have any fresh injury concerns to contend with.
Therefore the only players who may not be considered are returning long-term absentees David Bell (toe) and Callum Ball (foot), who are both on the brink of full fitness.
Joe Garner is in line to make his Preston debut.
