I guess I would vote for you getting another tag if you were able to prove something was wrong with the deer to the DNR and went through the trouble of taking it to them. I'd think they'd be happy you were taking a sick deer, especially if infectious, out of the herd. Easy to say tough luck if it isn't you. What if you were only able to have one tag where you were at and had no idea the deer was sick when you took it? I guess no venison for you for at least another year.
