The former Tottenham goalkeeper has not figured for the first team since January but is now the club's number one again after Carl Ikeme's loan spell from Wolves came to an end this week.
If Warnock decides to include a keeper among his substitutes then Shane McWeeney will be added to the squad, otherwise midfielder Mikele Leigertwood will don the gloves in an emergency.
Elsewhere, striker Tamas Priskin could return but defender Matt Connolly will probably miss out again with an ankle injury.
Dusko Tosic will push for his debut at left-back after joining on loan from Portsmouth recently.
Midfielders Gavin Mahon and Martin Rowlands are still out with knee injuries.
