Summerfield's substitution led to an introduction - and debut - for 17-year-old right-back Ryan Leonard with Karl Duguid moving into midfield, a role he occupied last season.
Head coach Paul Mariner has since recalled midfielder Yoann Folly from his loan spell at Dagenham & Redbridge as cover for his injury-hit squad.
Central defender Kari Arnason (hip), on-loan Burnley full-back Richard Eckersley (ankle) and winger Craig Noone (knee) are also ruled out along with right-back David McNamee (hamstring). Winger Alan Judge, who was substituted on Saturday with a groin injury, should be fit but defender Chris Barker (hamstring) is rated 50-50.
The game had to be rescheduled after the initial clash had to be abandoned due to a waterlogged pitch on November 28 with Barnsley leading 4-1 with over half an hour left.
