Karty (groin) is listed as active Sunday's game against the 49ers, Cameron DaSilva of USA Today reports.
Karty approached the contest listed as questionable after returning to a limited practice Friday. He'll be available Sunday, but the 0-2 Rams' kicker will be working behind a short-handed offense that is minus its top two wide receivers, Cooper Kupp (ankle) and Puka Nacua (knee).
