Entirely too many variables to give you an accurate estimate. How was the pork loin treated before freezing, how cold is the fridge, how old is the pork? You should be good a couple of days but I wouldn't go much beyond that.
Al & Dan know their stuff. Raw meat in the fridge is scary stuff. If it was still cryovaced, and had a sell by date on it that would be different, but since you unwrapped it & rubbed it down I would cook it in 24 hours. But then I'm kinda paranoid about these things nowadays. Back when I was a kid I would eat raw hamburger while my Mom was making patties, I don't do that anymore either!
