McFadden strained his abdomen during the divisional-round victory over the Baltimore Ravens, but he played Sunday against the New York Jets in a diminished role. Sanders, a rookie, has an injured foot. Polamalu has been bothered by an Achilles' tendon injury, but it isn't unusual for the All-Pro to sit out midweek practices.
All three are questionable for the Super Bowl, but there are serious doubts if any will be able to play.
