We now have clarity that Raheem Mostert will miss the entire rest of the season after landing on IR. It's unfortunate for Mostert - who simply can't stay healthy - and we wish him a speedy recovery. As for the fantasy fallout, Elijah Mitchell seems to be the next option up after Kyle Shanahan mysteriously benched Sermon in week one against Detroit. Mitchell looked great against the porous Lions run defense and it appears that he's going to be given the opportunity to win this starting job here in San Francisco. That's at least the perception...we have no idea what the reality is and what Shanahan will choose to do. Mitchell can be viewed as a mid-range RB3 this week that has the potential to hit big or has the potential to somehow take a backseat to Sermon, who probably figures to be active in this one.
