RG Dominick Puni suffered a PCL injury and is uncertain to be ready for Week 1. RBs Patrick Taylor, Corey Kiner also hurt.

The 49ers played their starters to open Saturday's game against the Raiders, but one member of the group had to leave with an injury.

The only thing that matters during the preseason is getting out of these games healthy. We didn’t need to see the San Francisco 49ers’ starters for more than a series. However, Dominick Puni did not come out with Connor Colby and Spencer Burford, a couple of other offensive linemen who started the game.
