San Francisco 49ers head coach Kyle Shanahan believes the locker room vibes are much better compared to last season. Aside from the constant injuries leading up to the looming 53-man roster decision, a lot has changed in San Francisco.

The San Francisco 49ers will officially be without wide receiver Demarcus Robinson to start the season, as head coach Kyle Shanahan confirmed on Wednesday that the free agent signee is getting suspended for the first three games of the year.

Robinson received a three-game suspension Wednesday, Kyle Shanahan said ( via KNBR ). Although this is certainly not surprising, it deals another blow to a depleted San Francisco 49ers receiving corps.

Purdy spent the offseason working on little things to improve his game after securing the biggest raise in NFL history.

Renardo Green and Isaac Guerendo were among those who returned for a practice in which Brock Purdy and Ricky Pearsall continued to connect.

The San Francisco 49ers are bringing back a familiar face under center. According to the Athletic's Matt Barrows, the 49ers are signing quarterback Nate Sudfeld after Sudfeld threw in a wide receiver workout Monday.
