The Rams fell to the Arizona Cardinals 27–3 on Sunday, with Nick Foles starting at quarterback. Keenum was active for the game, but listed as the backup as he recovers from a concussion he sustained in the Rams’ 16–13 loss to the Baltimore Ravens on Nov. 22.
On the Rams’ final drive against the Ravens, Keenum was slammed to the ground on a hit and had the back of his head bounce off the turf. He was immediately seen holding the sides of his head and then failing to stand as a teammate attempted to pull him up.
The game against the Ravens was Keenum’s first start of the season, after Fisher made the decision to bench Foles. Keenum went 12 for 16, throwing for 136 yards and a touchdown against Baltimore but the concussion forced the Rams to start Foles in the last two games.
Foles struggled against the Cardinals, going 15 for 35 and throwing for 146 yards and an interception.
Kickoff between the Rams (4–8) and the Lions (4–8) is set for 1:00 p.m. ET on Dec.13.
