Instead of relief, the week keeps bringing more bad news regarding injuries for the Steelers.
Center Maurkice Pouncey, who returned to play last Sunday after missing two games with a high ankle sprain, did not practice Thursday because his ankle took a turn for the worst.
"I practiced the other day and toward the end I got sore," Pouncey said after practice Thursday. "Today, I came in and my ankle was real sore, so I don't know what the turnout is going to be. Right now, I'm not practicing."
Pouncey was clearly not happy about the turn of events. In previous weeks, he predicted he would play even though he wound up missing two games because of it.
"I'm aggravated with it, I'm kind of stressed about it. I mean an injury prolonged this long is aggravating. Hopefully, I can push through it and see how this week goes."
Offensive coordinator Bruce Arians said he is concerned about Pouncey's chances of playing Sunday. Doug Legursky would start at center Sunday in Denver if Pouncey cannot play.
In the meantime, Ben Roethlisberger returned to practice on his own high ankle sprain and Arians was a little more encouraged about that.
"A little better," Arians said. "He got some of it. He's moving around okay, not as good as he was, but okay."
Three other starters did not practice at all: James Harrison (toe), Brett Keisel (groin) and Troy Polamalu (calf). All are expected to play Sunday.
Backup tackle Jonathan Scott was limited in practice because of a back injury that is new.
