This from Ed. B. of the P-G
Some better news for the Steelers today because James Harrison went through another full practice, his teammates said, and Troy Polamalu did as well.
The chances now exist that both Pro Bowlers could return to a defense that has been underperforming without them.
Since he still is on the active roster, I agree "chances now exist" Harrion could play on Sunday, but until he makes it through several consecutive practices without his knee acting up I will not gte my hopes up.
