The San Francisco 49ers are taking a closer look at their running back depth after Jordan James’s injury, bringing in three backs for a workout on Thursday. The group included Raheem Blackshear, Khalil Herbert and Owen Wright.

Herbert stands out as the most recognizable name in the workout group because he is a former Bears starter. His visit suggests San Francisco is exploring experienced options as it evaluates how to reinforce the backfield.

Blackshear and Wright also joined the session, giving the 49ers multiple styles and levels of experience to review. At this stage, the workout appears to be part of the team’s effort to assess available help rather than a confirmed roster move.

With James sidelined, San Francisco’s decision to host several running backs points to a practical search for insurance and competition at the position. The 49ers now have fresh information on three free-agent options as they consider their next step.
