Addai still uncertain in Colts' weekly update

The Colts just sent out their weekly Tuesday injury update. Here it is in its entirety:

"Defensive back Bob Sanders (biceps) will be out this week against Dallas. Wide receiver Austin Collie is improving and his practice role will be determined as the week progresses. Collie suffered a concussion at Philadelphia on November 7. After being cleared medically to participate at New England on November 21, he encountered symptoms from his previous injury, though there was no recurrence. Running back Joseph Addai progressed to practice last week for conditioning purposes. Addai will do so again, but a timetable for a full return to action is uncertain. The club has waived wide receiver Brandon James and signed wide receiver Taj Smith. Linebacker Cody Glenn will be placed on injured reserve after suffering a neck injury last week against San Diego."

The lack of a mention of Gary Brackett and Clint Session suggest the linebackers could have a chance to return, which Bill Polian indicated in his weekly radio show. Same for Mike Hart, who practiced some last week.
