The on-loan Tottenham midfielder is struggling with a tight hamstring and is unlikely to be risked.
Former Manchester United youngster Michael Stewart could be handed a full debut in place of Perrett or Therry Racon could move inside paving the way for Kyel Reid to start on the wing.
Veteran defender Gary Doherty may return to the starting line-up after recovering from illness and striker Joe Anyinsah (ankle) will be checked over, but winger Johnnie Jackson (Achilles) is unlikely to play again this season.
Young left-back Carl Jenkinson is still being overlooked having turned down a new contract and been linked with a summer move to Arsenal.
