Breida (ankle) wasn't on the field for Thursday's practice, Matt Barrows of The Athletic reports.
Ian Rapoport of NFL Network reported that Breida would likely be sidelined for 1-to-2 weeks after aggravating a low-ankle sprain in Monday's loss to the Seahawks, so it shouldn't come as much of a surprise that he's been withheld from both of the 49ers' first two practices of Week 11. With Breida trending toward an inactive status this weekend versus Arizona, Tevin Coleman -- who was also absent from Thursday's practice due to a non-injury-related matter -- is expected to take on a more pronounced role in the San Francisco backfield.
