Adding to the concern, star left tackle Trent Williams was questionable heading into Sunday's game after dealing with a knee issue last week, and nearly didn't play.
The 49ers spent time on Tuesday looking into their offensive line options, working out the following players:
- Le'Raven Clark
- Chris Hubbard
- Brandon Parker
- Zachary Thomas
- Matt Waletzko
Both Hubbard and Parker are familiar faces, having spent some time with San Francisco in 2024.
The 49ers will continue to closely monitor their injuries, with roster moves possible ahead of Sunday's divisional clash against the Arizona Cardinals.
