Warnock has no new injury or suspension worries following Saturday's 2-2 draw at promotion rivals Cardiff, while defender Fitz Hall is pushing for a return to the starting line-up.
Hall stepped off the substitutes' bench for the final 10 minutes against the Bluebirds after missing the previous two games due to a groin injury.
Striker Patrick Agyemang is pushing for a recall after replacing Tommy Smith for the final 20 minutes on Saturday, while midfielder Akos Buzsaky, striker Rob Hulse and winger Hogan Ephraim - all unused substitutes at Cardiff - are among those hoping to feature.
Defender Peter Ramage (cruciate), winger Lee Cook (knee) and striker Jamie Mackie (broken leg) remain long-term absentees.
