Stafford questionable after limited participation in practice

The Detroit Lions labeled Matthew Stafford as questionable to face the Tennessee Titans after the quarterback was a limited participant Friday at practice, according to the injury report.

Stafford has been battling rib and thumb injuries, and sat out practice entirely Wednesday and Thursday. The 32-year-old has thrown for 3,522 yards with 22 touchdowns and nine interceptions over 13 games this season.

The sinking Lions will take a 5-8 record into Week 15, searching for only their third win since the beginning of November.

Center Frank Ragnow, who didn't practice all week while dealing with a reported throat fracture, was downgraded to out after initially being deemed questionable.
