Defensive tackle Sammie Hill (toe) has been ruled out for Sunday’s game against the Chicago Bears. He hasn’t practiced all week which leaves the Lions slim at the defensive tackle position with Corey Williams and Nick Fairley on injured reserve.

Andre Fluellen is likely to get the start. Fluellen was cut after training camp and then re-signed on Dec. 12 after Williams was placed on injured reserve.

Tight end Brandon Pettigrew returned to practice Friday for the first time since he sprained his ankle at Green Bay on Dec. 9. It was on a limited basis. He has missed the last two games and is doubtful for Sunday.

 Safety Louis Delmas (knee) returned to practice after sitting out all week. He’s done this for the last two weeks which allowed him to play. He’s questionable against the Bears.

 Chris Houston (hamstring/hip) was limited on Friday and is also questionable.

 Calvin Johnson (knee/ankle) did not practice, but was on the field. He’s probable to play on Sunday.

 Defensive end Kyle Vanden Bosch, who didn’t practice, has been taking rest days on Fridays.

 For the Bears, safety Chris Conte (hamstring) and linebacker Blake Costanzo (calf) are out while linebacker Brian Urlacher (hamstring) is doubtful; running back Armando Allen (knee) and defensive tackle Henry Melton (chest) are questionable.
