The Rams placed wide receiver Cooper Kupp on the team's reserve/COVID-19 list on Tuesday.
Kupp's status for Sunday's Week 17 matchup with the Cardinals has not been announced, though it is unlikely he'll play in the regular-season finale.
Los Angeles is now without two major offensive pieces in Week 17. Quarterback Jared Goff will not play after undergoing thumb surgery. He would likely return to the field if the Rams reach the postseason. Backup John Wolford will make his first NFL start on Sunday.
The Rams are still eligible for the postseason despite currently sitting second in the NFC West at 9–6.
