Detroit Lions quarterback Matthew Stafford was a limited participant in Friday's practice and is questionable for Sunday's home game at the Tennessee Titans with rib and right thumb injuries.
Stafford did not practice at all on Wednesday or Thursday. If he can't go, Chase Daniel will start for the Lions (5-8) against the Titans (9-4) in Nashville.
Stafford, 32, sustained the rib injury in the fourth quarter of the Lions' Week 14 loss to the Green Bay Packers. He has been dealing with a partially torn ligament in his thumb since a Week 10 win against Washington.
