He did open the door on the return of safety Troy Polamalu, albeit in Week 11 against the Baltimore Ravens. He didn't make mention of right tackle Marcus Gilbert's return - both he and Polamalu have missed the last several games - but said both will practice on a limited basis this week.
Tomlin mentioned running back Chris Rainey, who suffered a rib injury during the Steelers' Week 9 win over New York, could play against the Chiefs, but if he doesn't, WR Emmanuel Sanders will again return kicks and punts.
Sanders filled in quite well against the Giants, taking a punt back 63 yards. He was a light punter's touch away from scoring as well.
Brown would be again replaced by Jerricho Cotchery, and would likely mean an increase in targets to the only receivers remaining. It would also likely mean a call-up from the practice squad - either David Gilreath or Toney Clemons.
