Benson is appealing his suspension and the decision hasn't been handed down yet, so he may be available for the Bengals. I saw they worked out Clinton Portis today...probably insurance should the league deny Benson's appeal.

McGee should be back sooner than Williams, but who knows with hamstrings...Williams seemed to be getting quite a bit of playing time before he went out, not only on defense but on special teams as well.
