Christian McCaffrey might be out longer than expected with the San Francisco 49ers. A few months ago, Christian McCaffrey and the San Francisco 49ers lost the Super Bowl in overtime against Patrick Mahomes and the Kansas City Chiefs.

Shortly before the start of the San Francisco 49ers’ season opener against the New York Jets on Monday Night Football, Christian McCaffrey was listed as inactive due to an ankle/Achilles injury. McCaffrey was initially listed as questionable for Monday’s tilt with the Jets after participating in practice on a limited basis during the week.

Now, NFL Network insider Ian Rapoport has unveiled a likely worst-case timeline for McCaffrey to return to game action. According to Rapoport on Sunday, September 15, McCaffrey "may need as much as 6 weeks to heal from his Achilles tendinitis." The insider also noted it could need "potentially more" time to fully recover.
