PITTSBURGH -- Steelers defensive end Brett Keisel missed a third consecutive day of practice because of a neck injury and might not play Sunday at Miami.
Keisel is listed as questionable, but Steelers players rarely play after not practicing all week.
Steelers safety Troy Polamalu (left knee) practiced on a limited basis for the third day in a row Friday and isn't expected to play. On Wednesday, Polamalu said it wasn't realistic for him to expect to play for the first time since Nov. 15 without a full week of practice.
Left guard Chris Kemoeatu (wrist) also was limited in practice Friday and is listed as questionable, as is Polamalu.
Wide receiver Hines Ward practiced after sitting out Thursday with two sore hamstrings.
