Pro Bowl cornerback Antoine Winfield was officially listed as doubtful for Sunday's game at Pittsburgh after missing three straight days of practice. Per league rules, doubtful means there is only 25 percent chance that Winfield will play.

If Winfield is out, there is a good chance that nickel back Benny Sapp will start at left corner and then move inside in nickel situations. Karl Paymah would play cornerback in nickel situations. Paymah filled in after Winfield got hurt last week.

Darius Reynaud also is listed as doubtful because of a lingering hamstring injury.

Safety Madieu Williams (quadricep), Percy Harvin (shoulder) and safety Husain Abdullah (back) are all questionable. All three had limited participation in practice this week.

As expected, running back Adrian Peterson is listed as probable after twisting an ankle last week. Peterson had full participation in practice Friday.

For the Steelers, safety Troy Polamalu (knee) and running back Rashard Mendenhall (knee) are listed as probable.
