Chantler, who can play at left-back or in midfield, has missed the last three games due to ankle ligament injury and Welsh has seized his chance after making his first start of the season in the recent home draw with Scunthorpe.
Welsh retained his place in last week's win at leaders Tranmere and with Matty Robson set to continue in defence, the 29-year-old should line up again in midfield.
Striker Rory Loy is hoping to retain his place up front after scoring his first goal in over a year last week following his year-long lay-off with a broken leg.
Experienced defenders Mike Edwards and Peter Murphy are pushing for recalls and teenagers Dave Symington and Mark Beck are set to resume on the substitutes' bench.
