Christian McCaffrey Faces Backup Battle as 49ers Training Camp Begins

Christian McCaffrey remains the undisputed leader of the San Francisco 49ers' backfield as training camp begins on July 14, 2026. But the team's reliance on the 30-year-old running back raises questions about depth and durability heading into the season.

Who’s competing for backup RB spots?

The 49ers' depth chart behind McCaffrey is wide open. Jordan James, last year’s No. 3 back, faces competition from rookie Kaelon Black, a third-round pick, and Isaac Guerendo, a 2024 fourth-rounder still recovering from injury. Sincere McCormick and Patrick Taylor Jr. round out the group, but special teams contributions may decide who makes the final roster.

Why does this matter for McCaffrey’s workload?

McCaffrey led the NFL in touches last season for the third time in his career. Historically, heavy workloads have led to injuries-he played just three games after his first touch-leading season and five after the second. Finding a reliable RB2 is critical if the 49ers want to keep McCaffrey fresh for a deep playoff run.

What’s the biggest question mark at RB?

The 49ers need a backup who can both spell McCaffrey and step into a starting role if needed. James, Black, and Guerendo will battle for that role, but none have proven they can handle a significant workload. Special teams play could also factor into who earns a roster spot.

How many RBs will the 49ers keep?

San Francisco typically keeps four running backs plus fullback Kyle Juszczyk. McCaffrey, Black, James, and Guerendo seem likely to fill those spots, but Guerendo’s health and Taylor’s special teams experience could shake things up. The competition will be fierce as the 49ers aim to balance McCaffrey’s usage with playoff aspirations.
