Polamalu did practice last week, leading up to the game against the Lions, but it was determined that it would be best to hold him out another week.
There will probably not be such luck for the Cleveland Browns, who Polamalu is expected to play against this Sunday.
Fast Willie Parker, is also expected to practice for the first time in two weeks, after suffering a Turf Toe injury against the Bengals.
Parker will be trying to save his starting job, after second year pro, Rashard Mendenhall has had the two best games of his young career in the absence of Parker.
Mendenhall rushed for 165 yards two weeks ago against the San Diego Chargers, and another 77 this past week against the Lions.
It will be interesting to see if Parker returns as the starter, and how short his leash will be if he does get the nod.
Aaron Smith damaged his right rotator cuff against the Lions Sunday, and as coach Mike Tomlin reports, this injury may be "significant." Aaron Smith is not only an anchor on the right side of the line, but a team leader that will be missed.
Chris Kemoeatu, who injured his ankle last week against the Chargers, managed to come back and start against the Lions. Kemoeatu made it through the Lions game, without re-injuring his ankle, and is expected to have a full week of practice.
Andre Frazier, who was injured by Lawrence Timmons, while they were both making a special teams tackle, and Trai Essex will be limited in practice.
