Left-back Warnock was sent off for a late second yellow card in the midweek defeat at Reading and will sit out a one-game ban, while right-back Lee Peltier is struggling to overcome a groin problem that ruled him out on Wednesday night.
Another defender, Aidy White, was recalled to the substitutes' bench at Reading and could come into contention if Peltier misses out again and Byram is deemed not ready. Otherwise, McDermott has no new major selection issues.
