ALLEN PARK, Mich. -- Detroit Lions quarterback Matthew Stafford is questionable for Sunday's game against the Tennessee Titans, while center Frank Ragnow has been downgraded to out.
Both players were injured in last weekend's loss to the Green Bay Packers.
Stafford suffered a rib cartilage injury in the fourth quarter when he was hit by Kenny Clark and had to leave the game. He did not practice Wednesday or Thursday and was not spotted working out during the open-to-the-media portion of practice Friday. He was listed as doing limited work.
