Allen Park, MI (Sports Network) - Detroit Lions safety Louis Delmas and defensive tackle Nick Fairley are listed as questionable for the team's Thanksgiving Day matchup against the Houston Texans.
Delmas has missed the team's last three contests with a left knee injury, but returned to practice on a limited basis over the last two days.
Fairley appeared on the injury report after sitting out Wednesday's session with an illness.
Cornerback Drayton Florence was also listed as questionable after sustaining a concussion during last week's 24-20 loss to Green Bay. He returned to practice on a limited basis on Wednesday after missing the previous two days, but it's still unclear if he's been cleared for contact.
Defensive tackle Corey Williams (knee/illness) and cornerback Jacob Lacey (foot) both missed practice on Wednesday and are questionable for Thursday's tilt.
Left tackle Jeff Backus has started 187 consecutive games since being drafted by the Lions in 2001, but is listed as doubtful with a hamstring injury.
Wide receiver Titus Young was ruled out earlier in the week as a disciplinary measure after being sent home from the team's facility on Monday for behavioral reasons.
Wide receiver Calvin Johnson (knee/thumb), defensive end Cliff Avril (back) and defensive tackle Ndamukong Suh (knee) are listed as probable.
