The outside linebacker is listed as questionable with an ankle injury. The Rams held Miller out of the Nov. 7 loss to the Tennessee Titans.
Miller's ankle injury was worse than the Rams suspected when they acquired him from the Denver Broncos earlier this month for second- and third-round draft picks.
Miller recorded 4.5 sacks in seven games this season with Denver. His last game for the Broncos was on Oct. 21 in a loss to the Cleveland Browns when he suffered the ankle injury.
An eight-time Pro Bowl selection and three-time All-Pro, Miller leads all active players with 110.5 sacks in his career.
