49ers Roster Shifts After Multiple Running Back Injuries

The San Francisco 49ers are facing significant challenges in their running back depth chart due to injuries, notably to Isaac Guerendo, who has been sidelined multiple times since being drafted and is currently out for several weeks with a shoulder injury. This situation has opened up opportunities for rookies Jordan James, a powerful and patient downhill runner from Oregon, and undrafted prospect Corey Kiner from Cincinnati, both of whom are competing to secure the backup role behind starter Christian McCaffrey. James, despite a late knee injury, has impressed in training camp and may see increased playing time as Guerendo recovers, while Kiner is viewed as a potential breakout candidate, continuing the 49ers' trend of developing undrafted backs into valuable contributors. Head coach Kyle Shanahan remains cautious, requiring consistent high-level performance from these rookies to earn a spot, especially given the unreliable health record of Guerendo. The 49ers' running back depth is critical due to McCaffrey's injury history, making the backup position a pivotal role for the team's offense in the upcoming season. Meanwhile, the team is also dealing with injuries in other areas like the defensive line, but the running back situation remains a focal point as the preseason progresses.
