Mike Tomlin said today that Troy Polamalu passed all of his concussion tests and will be ready to practice Wednesday in preparation to face Arizona on Sunday.
Polamalu sat out part of the fourth quarter of last Sunday's win against Jacksonville after getting a knee in the head while tackling Maurice Jones-Drew.
In other news, guard Chris Kemoeatu, linebacker Jason Worilds and Marcus Gilbert are expected to return to the lineup.
Tomlin said he will make a decision later this week about whether it will be Worilds or Lawrence Timmons at outside linebacker in place of James Harrison.
Harrison remains out, as do Aaron Smith and Casey Hampton.
Doug Legursky will also be out several weeks after suffering a dislocated toe against the Jaguars.
Chris Hoke will likely be back this week to replace Hampton. Hoke suffered a stinger in the first half against Jacksonville and did not return to the game.
