Jordan Mason of the San Francisco 49ers is facing a likely trip to injured reserve due to a high-ankle sprain, which has left the team to rely on rookie Isaac Guerendo and veteran Patrick Taylor in the backfield. Mason had previously shown promise earlier in the season when he stepped up during Christian McCaffrey's absence, but his role has diminished since McCaffrey's return. The 49ers have also added Ke'Shawn Vaughn to their practice squad as they navigate this injury situation.

• Jordan Mason is likely heading to IR due to a high-ankle sprain.
• The 49ers will rely on Isaac Guerendo and Patrick Taylor in the backfield moving forward.
• Mason had previously excelled in a lead role when McCaffrey was injured.
