"Indianapolis Colts running back Joseph Addai says his injured left shoulder is progressing each day and he hopes to return to the lineup soon.

When? That's still in question.

The team's leading rusher, who has missed the past two games with the injury, said he is unsure of when he will return during a fan promotion today at the FedEx office on Monument Circle.

"Every day, with that nerve, the injury is so different," he said of the shoulder, which is still painful and has yet to regain full range of movement. "Every day is that much more hope. If you ask me, 'Joe, when you think you'll be back?' I'll try to be back this game."

The Colts (5-3) host Cincinnati (2-6) at 1 p.m. Sunday."
