Allen Park, MI (Sports Network) - Detroit Lions safety Louis Delmas, defensive tackle Sammie Hill and defensive end Cliff Avril are listed as questionable for Sunday's game against the Philadelphia Eagles.
Delmas, who was a limited participant in practice on Wednesday and Thursday, sat out Friday with a knee injury.
Both Hill (toe) and Avril (back) were only able to take limited reps in practice on all three days this week.
Linebacker Stephen Tulloch was listed as probable, as he is still dealing with soreness in his knees associated with tendinitis.
Wide receiver Titus Young (knee) is probable after enjoying full participation in practice the last two days, while linebacker Travis Lewis (quad) is listed as probable after full participation all week, and tight end Brandon Pettigrew (knee) is probable after limited reps on all three days.
