Kerryon Johnson

49ers' RB attrition is wild. Jeff Wilson, Raheem Mostert, Trey Sermon, Elijah Mitchell, JaMycal Hasty all now hurt. TBD on the Week 3 status of the final three.

What does SF do this week? Depends on health developments, but seems there's a good chance they start with a Kerryon Johnson practice squad call-up.

Sermon, Mitchell and Hasty were all injured in Week 2. Sermon appeared to be dealing with a head injury which could cost him time depending on protocols. Mitchell is dealing with a shoulder injury but the hope is he avoided something major. Meanwhile, Hasty is dealing with an ankle injury. It will be a situation to watch as the week goes on leading to Week 3. One problem for owners is the 9ers play on Sunday night against the Packers, so any game-time decisions will cause a need for backup plans.
