Karty (groin) officially is listed as questionable for Sunday's game against the 49ers, Gary Klein of the Los Angeles Times reports.
If Karty is unable to play through his groin injury, Tanner Brown would take over kicking duties for Los Angeles. Scoring opportunities could be hard to come by Sunday for a Rams offense without its top two wide receivers Cooper Kupp (ankle) and Puka Nacua (knee) against San Francisco's stout defense.
