49ers running back Christian McCaffrey missed practice on Tuesday due to stiffness in his back but is expected to play in Saturday’s critical NFC West matchup against the Seahawks. Coach Kyle Shanahan indicated the issue is not serious, and McCaffrey confirmed it himself. Despite experiencing back discomfort during Sunday’s game against the Bears, he played effectively, contributing 181 yards and a touchdown. McCaffrey emphasized the importance of the upcoming game as the team aims for the NFC West title and a top playoff seed.
