Niners LB Tatum Bethune suffered a high-ankle sprain in Sunday's win over the Cardinals. HC Kyle Shanahan said Monday that they expect Bethune to miss multiple weeks but that he probably won't hit IR because of the Week 14 bye.

Niners LB Fred Warner fractured and dislocated his right ankle in Sunday's loss to the Buccaneers, HC Kyle Shanahan announced after the game. He'll have surgery and miss the rest of the season.
