Brian Little said: "Obviously with Mike and Ben missing we have a little dilemma in the full-back department but we have options.
"Mark Greaves has played a lot of games in that position while Ben Morley is an especially good young player who is more than capable of doing the job.
"Whatever team I pick they'll know that we need a good result away from home and that's the focus for everybody."
Morley was given 10 minutes on Saturday coming off the bench, and Little said he would have "no qualms in selecting him."
Ian Goodison has returned to training following a leg injury and could play. Meanwhile Justin Whittle is out with a hamstring and Gary Alexander is suspended.
Expected line-up (4-4-2): Musselwhite; Morley, Goodison, Wicks, Holt; Williams, Sneekes, Greaves, Beresford; Roberts, Dudfield.
Subs from: Glennon, Mohan, Bloomer, Van Blerk, Johnsson, Matthews, Whitmore, Rowe.
