Colts put rookie RB Hart on IR; Addai limping

To make room on the active roster for Dawson, the Colts waived recently signed defensive back Nick Graham.

There was some positive injury news for the Colts. Outside linebacker Tyjuan Hagler, who has been on the physically unable to perform list with a torn pectoral muscle, practiced for the first time Wednesday.

Starting guard Ryan Lilja, also on the PUP list, however, still has not started practicing since having offseason surgery on his right knee.

The team has three weeks to activate Hagler and Lilja or they will miss the rest of the season.

Bob Sanders, the 2007 defensive player of the year, may return in the next few weeks. Sanders hasn't played since spraining his right ankle in Week 2 against Minnesota.

"I doubt that he'll practice this week, but when he can run, he'll be out there," Dungy said. "It's just the high ankle sprain that's keeping him out."
