The 31-year-old has not figured this season after having an ankle operation last summer, but he will get a run-out for the club's under-21s against Basingstoke on Thursday night to build up his fitness.
Manager Nigel Adkins told the club website: "Ledge has been a top, top pro - it's been so frustrating for him.
"He's going to get a planned 45 minutes, no more than that. So all being well he will come through that unscathed.
"His attitude has been exemplary. I cannot speak highly enough of him."
