Clinton Portis 50/50 for the Dallas game, injury updates

[calia]

If we do not have Portis (or have him at less than 100%), with Betts coming off an injury and Alexander having his best years behind him (and showin rust), this game scares me. Demarcus Ware may be in our backfield all day if we're forced to throw all the time -- the Steelers LBs certainly spent a lot of time there. To me, this game will come down to whether our D can (finally) force some turnovers and whether we can sustain some drives even with a hobbled running game.
