Allen Park, MI (SportsNetwork.com) - Detroit Lions running back Reggie Bush and left tackle Riley Reiff are questionable for Thursday's Thanksgiving Day game against the Chicago Bears.

Bush has missed the last two games with an ankle injury. The USC product was limited in practice this week.

The 29-year-old Bush has carried the ball 53 times for 191 yards and one touchdown in seven games this season. He has also caught 26 passes for 169 yards.

Joique Bell has started the past two games. He has carried the ball 141 times for 490 yards and three touchdowns in 10 games this season.

Reiff was a limited participant in Wednesday's walkthrough after missing practice on Monday and Tuesday. He suffered a left knee injury on the first play of the Lions' 34-9 loss to the New England Patriots last weekend.

If Reiff can't go, expect rookie Cornelius Lucas to make his first start at left tackle.

Guard Larry Warford and defensive tackle Nick Fairley are both out with knee injuries for the Lions.
