The San Francisco 49ers have needed an offensive lineman to step up at guard and an undrafted rookie is doing just that through two preseason games.

The second preseason game versus the Las Vegas Raiders was more entertaining for the San Francisco 49ers than the first. Part of that is because the starters got a bit of action, but it's also because the 49ers had some players stand out.

Raiders rookie Ashton Jeanty proved he could deliver hits and absorb them at the NFL level. He rushed for a bruising 33 yards and a touchdown on seven carries in Las Vegas’ 22-19 preseason loss to the San Francisco 49ers on Saturday.

For the 49ers their health has become a greater concern than their preseason performance. They just need to make sure they have enough healthy bodies to keep their key starters out of harm's way. More than 20 players missed their preseason opener vs. the Denver Broncos with injuries, and that number could rise Saturday when they face the Raiders.

Second-year starting right guard Dominick Puni, one of the bright spots of an otherwise grim 2024 season for the 49ers, is expected to miss multiple weeks with a suspected PCL injury. It appears the injury occurred after he was rolled up on during Jake Moody’s first quarter field goal attempt.

The San Francisco 49ers managed to contain Las Vegas Raiders running back Ashton Jeanty during a joint practice Thursday.

Raiders head coach Pete Carroll has high praise for this crucial acquisition from the offseason after the loss to the 49ers.

Las Vegas Raiders rookie quarterback Cam Miller rounds out the Raiders' quarterback room. Miller completed two of his six passes in the Raiders' exhibition matchup against the San Francisco 49ers on Saturday.
