The San Francisco 49ers will be without running back Christian McCaffrey for at least three games due to Achilles tendonitis. Coach Kyle Shanahan stated that the situation is unpredictable, and they will monitor it day by day. McCaffrey was placed on injured reserve after struggling with his condition during practice.

In his absence, backup Jordan Mason performed admirably but lacks McCaffrey's versatility. The team hopes to manage McCaffrey's recovery without rushing him back, as he is key to their offensive success.
