San Francisco left tackle Trent Williams was carted to the locker room in the third quarter of Sunday's Week 3 matchup against the Arizona Cardinals. The 49ers said he was dealing with a stinger and listed him as questionable to return.
Williams anchors the offensive line, protects quarterback Brock Purdy's blind side and contributes to San Francisco's rushing attack. The team announced a stinger diagnosis, but no long-term injury was immediately announced.
San Francisco also entered the game without defensive end Nick Bosa, who was expected to miss multiple games after a calf injury. The team chose not to place him on injured reserve.
