San Francisco 49ers head coach Kyle Shanahan announced Wednesday on an impromptu conference call that he has fired defensive coordinator Steve Wilks.
The 54-year-old coach's tenure with the team ends after one season following the departure of DeMeco Ryans, who became the head coach of the Houston Texans. This news also comes one day after Shanahan told reporters that he expected all of his assistant coaches to return for next season.
This is a developing story and will be updated.
