Amidst a surge of defensive struggles over their past three games, the San Francisco 49ers have been searching for answers to get back to the dominant unit that spearheaded a 5-0 start.

The Niners made their biggest move last week, trading a compensatory third-round pick to the Washington Commanders for defensive end Chase Young. They're making another, much smaller move this week in the form of an elevator ride.

San Francisco defensive coordinator Steve Wilks, who is in his first year with the team, will move from the coach's booth upstairs to field level to call Sunday's game against the Jacksonville Jaguars, coach Kyle Shanahan announced Wednesday.
