Piece missing

I have a floor joist in the basement that has been cut to accomidate a cold air return. The 2x8 has a void measuring
4"x 16". I need to jack the floor (because it is saging at that spot) and sister the joist. I would like to know first, if it is safe to jack the floor, and second, how to go about doing it properly.
