Caretaker boss Guy Whittingham has no new injury worries following the narrow 1-0 defeat at Leyton Orient in midweek.
Whittingham has assured young full-back Dan Butler he will keep his place in the team despite his mistake gifting Orient their winner.

Experienced duo Patrick Agyemang and David Connolly will continue in attack.
