Steelers coach Mike Tomlin said Troy Polamalu, who has missed the past three games with a left knee injury, could return to practice Tuesday on a limited basis but isn't sure whether the All-Pro safety will play Sunday at Detroit.
"Troy's been doing well and progressing well," Tomlin said. "He may participate in a limited basis tomorrow in practice with a brace on for individual (drills), to see how he runs around and changes direction. Last week, he ran some in a straight line to pretty solid reviews. We'll take another step to see where he is.
"What that means to his game participation is unclear at this point. We'll get him back out there on the practice field and see how he responds to that."
