PITTSBURGH (AP) — Steelers coach Mike Tomlin says All-Pro safety Troy Polamalu should be "good to go" for Sunday's game against Arizona after passing a concussion test.

The Steelers removed Polamalu for the final two defensive series of a 17-13 win over Jacksonville with concussionlike symptoms. The team did it as a precaution after Polamalu took a knee to the head while tackling Jacksonville running back Maurice Jones-Drew.

Tomlin says Polamalu has been cleared for practice by team doctors. He added he had no issue with Polamalu talking to his family on a cell phone while still on the field Sunday. Tomlin said Polamalu wanted to assure his wife he was OK.

The Steelers (4-2) also expect left guard Chris Kemoeatu and right tackle Marcus Gilbert back. Both missed the Jacksonville game with injuries.
