Mostert out for the season

49ers RB Raheem Mostert announced on social media that he'll undergo season-ending knee surgery after consulting with multiple doctors. So, if you weren't already planning to, you can safely drop Mostert from all redraft rosters. San Francisco is left with Elijah Mitchell, JaMycal Hasty and Trey Sermon at RB. All 3 figure to be active for Week 2. It's also worth noting that RB Jeff Wilson (knee) is eligible to come off the PUP list in Week 7. You can see where all of those guys sit in our updated Rest-of-Season Rankings.
