Striker Murray has been sidelined since mid-August after undergoing hernia surgery and left-back Wright has been out for six weeks with a hamstring injury.
But both players came through a behind-closed-doors practice match this week and should be in the squad.
Full-back Jim McNulty is also back in training following an ankle injury, although Saturday's game may come too soon.
On-loan midfielder Arron Davies rested a hamstring problem earlier in the week and is fit again, defender Colin Hawkins has recovered from a broken nose and back-up goalkeeper Graeme Smith returns on the bench following an ankle injury.
But right-back Andrew Whing is still missing with a groin injury.
