The San Francisco 49ers made some changes under center for their preseason finale against the Los Angeles Chargers.

The 49ers' starting cornerback hurt his hamstring about four weeks ago and has not been practicing since. This has allowed the team to see Dallis Flowers and Darrell Luter under a microscope and may have improved the depth of the unit. Still, they need a healthy Green and he appears on track for week one.

The 49ers may target Commanders RB Brian Robinson Jr. to add depth behind Christian McCaffrey and strengthen Shanahan’s offense.

The 49ers have signed QB Nate Sudfeld to a one-year deal. In order to make room on the roster, the team placed RB Patrick Taylor Jr. on the Injured Reserve list.

The 49ers are signing a quarterback to help out as the NFL preseason nears its end. Nate Sudfeld previously played for the team.

The 30-year-old is a Super Bowl winner. He earned his ring with the Philadelphia Eagles in 2017, serving as a backup to Carson Wentz and Nick Foles during their title-winning season. He has since gone on to play for the Detroit Lions and the Niners.

Tyree Wilson made a handful of plays against the San Francisco 49ers that he has never made his entire NFL career originally appeared on A to Z Sports. We all know how big of a year this is for Tyree Wilson, the Las Vegas Raiders ' former No. 7 overall pick a few years ago. This, in many ways, can be a make it or break it season.

This is a significant blow to the 49ers' RB room since Taylor had secured a spot as a reliable third or fourth option who contributed on special teams. He posted a career-high 109 yards on 17 carries in San Francisco's Week 18 loss to the Arizona Cardinals last season.
