All-Pro safety Troy Polamalu has a calf injury and he will tread lightly in the early practices this week.
Coach Mike Tomlin revealed today that his star strong safety was injured in pregame warm-ups Sunday. He was not introduced before the game with his teammates because trainers were attending to him.
Tomlin did say that all indications are that he will be fine for Sunday's AFC championship game against Baltimore at Heinz Field.
Also, center Justin Hartwig injured a knee in the second quarter last Sunday and wore a brace on it in the second half. He too should be fine but limited in practice as well.
