Detroit’s defense will be without two key players for the second consecutive game Sunday when the Lions face the Packers and reigning MVP Aaron Rodgers at Ford Field.

Safety Louis Delmas (knee) and DT Corey Williams (knee) were listed among the team's inactives for Sunday’s game.

Williams hasn’t played since aggravating a knee injury during Detroit’s Week 9 win over the Jaguars. He'll be replaced by Nick Fairley, who will look to repeat a dominant Week 10 performance against the Vikings that coach Jim Schwartz called the best game of his career.

Delmas will miss his third consecutive game after re-aggravating a previous left knee injury during Detroit’s Week 8 win over Seattle. He will be replaced in the starting lineup by Ricardo Silva.

Silva will start alongside Eric Coleman, who was moved into a permanent starting role when Detroit placed S Amari Spievey (concussion) on injured reserve Saturday. Spievey had yet to pass concussion testing following an injury suffered during Detroit’s Week 7 loss to the Bears. His uncertain status made him the logical choice to be inactivated so a roster spot would be cleared for CB Drayton Florence, who was placed on the "IR with designation to return" list after breaking his forearm against San Francisco in Week 2. He practiced without incident for two weeks before being activated Saturday and is eligible to play against the Packers.
