Heat oil in heavy large skillet over medium heat. Add chopped bacon and cook through until brown, then transfer to bowl. Add sausage; sauti until cooked through and brown, breaking into pieces with spoon, about 8 minutes. Using slotted spoon, transfer sausage to large bowl. Add celery and next 6 ingredients to drippings in skillet. Sauti over medium heat until vegetables are soft, about 5 minutes. Discard bay leaf. Add mixture to sausage and bacon. (Can be made 1 day ahead. Cover; chill. Reheat to lukewarm before continuing.)
Preheat oven to 3500F. Butter 13x9x2-inch glass baking dish. Add bread to sausage mixture. Whisk milk, broth, cider and butter in bowl to blend. Mix into stuffing; season stuffing with salt and pepper. Mix in eggs; transfer to prepared dish. Lightly butter a piece of alumnium foil; cover with foil (butter side down) and bake for 30 minutes. Remove foil and cook through until brown, about another 20-25 minutes.
