Christian McCaffrey to MISS preseason!

49er star running back Christian mcaffrey has been diagnosed with a calf strain and he is unlikely to participate in this preseason and he's also likely to miss multiple weeks of practice and I've said it before and I'll say it again luckily it's the preseason and he has time to heal but he's also a running back that has a huge history of injuries and he's also the best running back in the NFL so hopefully this doesn't linger
