The San Francisco 49ers have placed running back Christian McCaffrey on injured reserve due to Achilles tendinitis and calf tightness. He is expected to miss at least the next four games, with a reassessment scheduled for October that could extend his absence. In his absence, Jordan Mason is set to take over as the starting running back for the 49ers.
- McCaffrey's injury is significant, impacting both his fantasy value and the 49ers' offense.
- Jordan Mason is a player to watch as he steps into the RB1 role.
