Antwan Barnes, OLB (hamstring)
Jared Gaither and Corey Liuget are the biggest names on this list, and both of them did some light work on the side on Wednesday before missing the rest of the week of practice. That's usually a sign that Norv won't play them, but those two are so important that he probably will if they're good enough to go.
Williams will play, and forearm injury won't bother a WR nearly as much as a leg or midsection injury would. The achilles injury might slow down Eric Wright a little, but he usually makes plays with his brain instead of his legs anyway.
