Blackburn loanee Alex Marrow looks set to miss out with an ankle injury and Owen Garvan serves the final game of his two-match ban.
Andy Dorman came on for Marrow at Doncaster last weekend and will be hoping for a start, although Alessane N'Diaye is another option.
Skipper Paddy McCarthy is still out with a groin injury so Anthony Gardner partners Claude Davis at centre-half.
Pablo Counago was recalled to the starting line-up against Rovers and responded by hitting the winner, so he should keep his place in attack.
Winger Sean Scannell is short of fitness following his knee injury and defender Lee Hills (knee) is still missing.
