EDGE Analysis

The rookie first-rounder ended up missing all three of the 49ers' preseason games due to a knee injury that he suffered in early August. Williams was able to log a full practice to open the week, indicating that he is on track to make his NFL regular-season debut against the Seahawks on Sunday. He's expected to see a prominent role on the 49ers' defensive front alongside Nick Bosa, Kalia Davis and Jordan Elliott.
