49ers coach Kyle Shanahan said Gracen Halton suffered a season-ending ankle fracture.

The fourth-round rookie finishes the year with 10 tackles, eight quarterback pressures and two sacks. Shanahan also told reporters that starting cornerbacks Renardo Green (back) and Deommodore Lenoir (foot) picked up injuries in today’s game against the Raiders. The defense has been hit hard by injuries this season. Hopefully, the cornerbacks are back before long.
