Tommy Stevens will have to remain on the roster

Because of the situation with Carolina, Tommy Stephens can never be put on the practice squad. Carolina will sign him as soon as they do that. That means he will have to remain on the roster. He will need to be on special teams and be a 4th TE. Do we release one of our special team players to make room for him? Who could he replace?
Not if he's terrible he won't be.
But, I suspect he would be asked to play at least 4 special team units and probably be counted on as a 5th WR or 4th TE on the roster
