Central defender Naylor missed the pre-season trip to Slovakia due to a hamstring problem, but is expected to be handed his first senior appearance of pre-season on Tuesday night.
Grayson said: "This is another good game for us. We've got a couple of training sessions out here and we play on Tuesday night and it's another important part of our pre-season."
Summer signing Billy Paynter (shin) and defender Jason Crowe (ankle) have not made the trip.
