Overview

• San Francisco traded a 2026 sixth-round pick for Brian Robinson Jr., who was installed as Christian McCaffrey's primary backup upon arrival.
• Shanahan said the staff placed Robinson ahead of Isaac Guerendo based on Robinson's proven résumé after Guerendo missed early camp reps with a shoulder injury.
• Guerendo opens the season in a competitive RB3 spot after a 2024 rookie year with 420 rushing yards, four touchdowns and 15 catches for 152 yards.
• The 49ers plan to manage a healthy McCaffrey's workload through a rotation, with younger backs Guerendo and Jordan James not expected to be featured to start.
• Team reports note Guerendo dealt with injuries and reported practice fumbles, and James' finger injury has further complicated the depth behind McCaffrey and Robinson.
