PITTSBURGH — Cornerback Bryant McFadden, safety Troy Polamalu and wide receiver Emmanuel Sanders returned to practice Friday for the first time since the Steelers' AFC championship victory.

McFadden strained his abdomen during a win over Baltimore in the divisional round but played Sunday in a diminished role. Sanders, a rookie, has an injured foot. Polamalu has been bothered by an Achilles' tendon injury, but it is not unusual for the All-Pro to sit out midweek practices.

All three — as well as left tackle Jonathan Scott (ribs) who has not practiced this week — are listed as probable for the Super Bowl Feb. 6 against Green Bay in Arlington, Texas.

Defensive end Aaron Smith (torn triceps) was limited in practice, as has been the case the past two weeks. Pro Bowl center Maurkice Pouncey (ankle) and special teamer Will Allen (knee) did not participate in any of the three practices this week.

All three are questionable for the Super Bowl, but there are serious doubts if any will be able to play.
