JaMycal Hasty (high ankle sprain) is week-to-week

Per Ian Rapoport, JaMycal Hasty is week-to-week after suffering a high ankle sprain against the Eagles on Sunday.

Fantasy Impact: After injuring his ankle on Sunday, an MRI revealed that the 49ers backup RB was diagnosed with a high ankle sprain leaving him week-to-week. With Raheem Mostert out for the season, Hasty banged up, and Trey Sermon suffering a concussion, the 49ers are thin at RB. The team worked out veteran T.J. Yeldon on Monday and the plan is to move forward with Elijah Mitchell as the starter.
