The Bears have placed rookie linebacker Michael Okwo on injured reserved for a shoulder injury. Okwo was injured during the Cleveland game. The impact of this could vary. Jamar Williams is the immediate backup for at least Lance Briggs and Brian Urlacher. I don't know who steps in should Hillenmeyer goes down.
The Bears filled the roster spot by signing Lousaka Polite. Polite has spent the last 3 years on the Dallas Cowboys. This signing was to give depth at fullback until Obafemi Ayanbadejo is back from his league mandated suspension.
