49ers Face RB Crisis as McCaffrey, Mason Hit IR with Injuries

The San Francisco 49ers face a significant challenge after running backs Christian McCaffrey and Jordan Mason were placed on IR due to injuries, potentially sidelining them for the rest of the season. Head coach Kyle Shanahan plans to elevate rookie Isaac Guerendo and practice squad member Patrick Taylor Jr. to fill the void, with Guerendo having a chance to secure a long-term role. The team may also consider bringing back Ke’Shawn Vaughn, who is familiar with their system, to bolster their backfield options.
