Safety Louis Delmas and cornerback Chris Houston may miss Detroit's season opener against the Rams this Sunday, according to the Detroit Free Press. Neither player took part in the open portion of Wednesday's practice.
Houston sprained his ankle in a preseason game against the Raiders on Aug. 25, and Delmas has been out for the past four weeks after undergoing arthroscopic knee surgery.
The Lions were hoping for a Week 1 return [for Delmas], but coach Jim Schwartz said last week it was imperative for him to practice this week if he is going to play against the St. Louis Rams.
John Welding, who replaced Delmas during the preseason, will start on Sunday if Delmas can't play. The team will likely use some combination Bill Bentley, Jacob Lacey and recent signee Drayton Florence as Houston's replacement.
Houston recorded 54 tackles and 5 interceptions in 14 games last season. Delmas had 51 tackles and 5 pass deflections in 11 games.
