If you look at question & answer #39 it should answer the first part of your question. Keep in mind that meat does not become unsafe to eat by being frozen for extended periods, but the quality and taste will certainly diminish to a point that you would not want to eat it.
After field dressing rinse with clean water and wipe dry with paper towels and cover the tenderloins with waxed paper or plastic wrap. Assuming that the daytime temperatures will not exceed 50 degrees and the hunt starts on Saturday, then you only have a little more than 24 - 36 hours to deal with. In this scenario you should be able to keep it cool by placing bags of ice in the cavity after you rinse it. Be sure it is hung out of the sun and preferably in a low lying area that remains cooler. (i.e, cedar swamp) Be sure that it is hung high enough that coyotes can't reach it.
Do not cover with or place it in a plastic bag or tarp when hanging, as this restricts air flow and the cooling of the carcass. I've seen deer that were skinned warm and put in plastic bags, only to start molding in 24 hours.
