After fouling out of Wednesday's Game 5, Rasheed Wallace was taken to the locker room because of a back injury. And with Game 6 lingering on Friday night, Sheed's status is very much in doubt. Writes Sports Illustrated's Chris Mannix on Twitter: "Wallace a game-time decision. Sheed's back pretty sore. Doc said he couldn't sit down yesterday, was having real trouble moving around. Would be a huge loss defensively." Indeed. Sheed's defense off the bench on Dwight Howard has been key in this series for the C's. If he's unable to go, it's possible Shelden Williams could get some run in the frontcourt Friday night.
