Jim Harbaugh announced on Monday afternoon that Ian Williams is out for the season with a broken ankle. On the second defensive possession of the game, Williams ended up being tripped by Seahawks offensive lineman J.R. Sweezy as the play was developing.
With Williams gone for the season, Harbaugh said that the team is exploring options at the nose tackle position. Glenn Dorsey will be the starting NT with Demarcus Dobbs backing him up on the depth chart. Harbaugh thought Dorsey played well when replacing Williams during the. The sixth-year defensive lineman recorded a sack and was okay against the run. He had the highest grade of any defensive linemen, according to Pro Football Focus.
The 49ers cannot add Will Tukuafu nor Lamar Divens to the roster as both players were waived/injured earlier this season.
Meanwhile, Harbaugh said Eric Reid is undergoing the required concussion protocol per NFL rules. Reid suffered a concussion when tackling Seahawks WR Sidney Rice on a play. He was able to walk off the field, but didn't finish the game. Harbaugh said Reid did not show signs of being symptomatic today which is a positive. Craig Dahl is the backup free safety behind Reid.
