Linebacker Christian Rozeboom joined Miller in being activated from the list Tuesday, leaving the Rams with 16 players remaining on the reserve/COVID-19 list.
Three starters remain on the list for the Rams and will not be able to play Tuesday night — right tackle Rob Havenstein, safety Jordan Fuller and tight end Tyler Higbee. Backup offensive tackle Joe Noteboom also remains on the list, which leaves the Rams without a clear option at right tackle.
The Rams (9-4) can tie the Arizona Cardinals for first place in the NFC West with a win Tuesday night at SoFi Stadium.
