Centre-half Stewart was suspended at the weekend and could be restored to the starting line-up, with Matt Connolly reverting to right-back and Peter Ramage dropping out.
Teenage striker Antonio German will start on the bench again despite his goalscoring cameo against the Swans.
Warnock has no new injury concerns although midfield duo Martin Rowlands and Gavin Mahon remain long-term absentees with knee problems.
Rowlands is out for the season but Mahon hopes to figure at some point during the run-in.
