Will my frozen turkey go bad?

I got a 15 lb erball turkey, it was in the freezer until Sunday night then I took it out and put it in a pan in the refrigerator so make sure it would thaw all the way before Friday. (we are having our Thanksgiving that day) But when I went in and touched the top of it, it felt like it had already thawed. Is it possible it has already thawed all the way? And if so will it go bad before Friday? I do not want to get people sick on the first Thanksgiving dinner I make.
