The defender missed the initial tie nine days ago due to a tight hamstring, with the same problem keeping him out of the 5-0 league defeat at Brentford on Saturday.
Ray's possible return aside, manager Steve Davis will probably be able to pick from the same group of players. Midfielder Ryan Colclough (hamstring) and full-back Matt Tootle (foot) are expected to resume training this week and could be back ahead of the derby clash against Port Vale.
Should Crewe get through they will host Preston in the second round next month.
