Preheat oven to 350 degrees.

Crumble oven-dried bread into a large bowl. Add rice and saltines.

Cook sausage in a large skillet until it starts to brown. Add celery and onion and saute until transparent, 5-10 minutes. Pour over bread and rice mixture. Add stock and mix well. Add salt and pepper, sage, and poultry seasoning. Mix well. Add the beaten eggs and melted butter. Mix well. Reserve 2 tablespoons of the stuffing mixture for gravy.

Pour stuffing into a greased pan and bake until cooked through and golden, about 45 minutes.
