Assuming that the meat never went into a danger zone and assuming that the wrap is airtight, and assuming that the meat stays in the safe zone while in the fridge, I would say safe for several weeks. I commonly purchase cryovac brisket and hold 3-4 weeks. It may need a bit of trim but no spoilage ever noted. Your beef roast should age the same. I would use a food saver vacuum pack.
