Harrison, who is recovering from right knee surgery, and Polamalu, who is dealing with a strained right calf, will have informal workouts this week.
Tomlin hinted Tuesday that neither veteran would have to practice to face the Raiders (0-2). Traditionally Tomlin likes his players to get at least one day of training in during the week leading up to a game before letting them loose on Sunday.
He's willing to make an exception, however, for two cornerstones of Pittsburgh's 3-4 defense.
"I handle all of those situations really on a case-by-case basis," Tomlin said, "with the understanding that the younger you are, the more inexperienced you are, the more practices are necessary before I consider utilizing you."
Meaning the well-established Harrison or Polamalu might not have to see the practice field. Harrison hasn't played since a playoff loss in Denver nine months ago, while Polamalu's calf didn't respond quickly to treatment last week after sustaining the injury in a season-opening loss to the Broncos.
The duo hardly was needed in a 27-10 romp over the New York Jets on Sunday. The Steelers (1-1) shut down New York in the second half, holding the Jets to just 91 yards over the final two quarters to win going away.
