Shane Cansdell-Sherriff was sent off for two bookable offences during Tuesday night's dramatic Johnstone's Paint Trophy triumph at Bury and must serve a two-match ban having also received his marching orders against Oldham in October.
A centre-back by trade, Cansdell-Sherriff was named at full-back in the absence of long-term victim Scott Laird (broken leg) and midfielder Joel Byrom filled the void as North End closed out a 3-3 draw and a penalty shoot-out victory.
David Buchanan is favourite to step into the left-back slot, although Westley could bring Chris Robertson back from suspension to partner new signing Luke Foster at centre-back and move Bailey Wright to full-back.
Elsewhere, attacking midfielder Jeffrey Monakana is available for selection after it was confirmed his 44th-minute withdrawal at Gigg Lane was a tactical decision.
