He is gone. Sa lavie. When I have only a shot down on a deer I either wait for a broad side shot or I put it on the spine between the shoulder blades. This way I ensure that my arrow will at least hit a lung. I have seen a deer with a nasty green uzzing arrow wond on its rump years ago. We shot it and burried it. It was obvious it had been shot at least week or so before we saw it. So most likley your deer is well gone.
