Mitchell (ribs) won't practice Wednesday, Matt Barrows of The Athletic reports.
Barrows notes that the hope is Mitchell gets some practice in during the week, so we'll revisit the running back's status no later than Thursday. In the 49ers' Week 8 win over the Bears, Mitchell was on the field for 36 of a possible 56 snaps on offense en route to carrying 18 times for 137 yards and a TD.
