Luke Daniels was sent off during Monday's 1-0 home defeat at the hands of Stockport and is banned for this weekend's clash.
Youngster Joe Collister is in line to deputise for on-loan West Brom stopper Daniels, but Parry is weighing up his options.
The physio said: "We've got a few irons in the fire. I've got full confidence in Joe but it's a massive game. If I'm able to bring an experienced goalkeeper in I will.
"Joe is going to be an excellent keeper but he's 17, and there's the knock on effect that we'd end up with young Andy Coughlin on the bench who is just 16.
"If anything happened the pressure on him would be immense, so that's why I'm looking at an experienced keeper."
