Los Angeles Rams free safety Taylor Rapp did not clear concussion protocol this week and has been ruled out for Monday night's wild-card playoff game against the visiting Arizona Cardinals.
Rapp suffered a concussion in the Rams' overtime loss to the San Francisco 49ers last Sunday. They also lost strong safety Jordan Fuller to a season-ending ankle injury in that game, meaning they'll be without both of their starting safeties Monday night.
The team lists backup running back Buddy Howell (hamstring) as doubtful. Receiver Van Jefferson (shoulder) is listed as questionable, but coach Sean McVay expects him to play and said everyone else should be available.
