The 49ers lost both first-string running back Christian McCaffrey and second-string running back Jordan Mason to injuries last week in Buffalo, leaving only rookie Isaac Guerendo available.
The 49ers shut down running back Christian McCaffrey this week and their 5-7 record suggests it won't be long before their playoff hopes are gone as well, but linebacker Fred Warner isn't looking to join McCaffrey on the sideline.
On Tuesday morning's PFT Live, I threw out the idea of the Bears ditching the normal approach to hiring head coaches and calling the 49ers to see whether they'd be willing to trade Kyle Shanahan.
