Raheem Mostert out for the season with knee injury

San Francisco 49ers running back Raheem Mostert will be out for the season after choosing to have knee surgery (per Raheem Mostert)

Fantasy Impact: Elijah Mitchell becomes the must-add player off waivers this week. He seems to have the keys to this backfield which we know is wildly productive from a fantasy standpoint. JaMycal Hasty is also worth a speculative add, especially for however long Trey Sermon remains in Kyle Shanahan’s doghouse. For Mostert, this is yet another season derailed by injury. Awful luck for him. Hoping for a full recovery.
