Assuming neither Rudolph or Washington can practice and play this week. Maybe same with Barron.
Means Lynch gets called up from the PS. Maybe a WR needs brought in to at least run in practice (like Mack @ TE last week and the QB this week).
So that is a couple of roster spots.
I am guess Elliot at OLB and Switzer at WR if the they need two. MAYBE Moncrief at WR if they want to get "bold" about it. Although I think they are going to try and work Moncrief back into the rotation and then flip him for something prior to the trade deadline.
