Nick Sorensen Won’t Return As 49ers Defensive Coordinator

The 49ers will be seeking their fourth defensive coordinator in four years. Nick Sorensen won’t return as the 49ers defensive coordinator in 2025, according to Matt Maiocco of NBC Sports Bay Area.

However, Sorensen’s stint in San Francisco may not be over. Maiocco adds that the 49ers are hoping they can keep the coach on Kyle Shanahan’s staff for next season. One option could be special teams coordinator, as Matt Barrows of The Athletic notes. The 49ers fired ST coordinator Brian Schneider the other day, and Sorensen served in that role during his time with the Jaguars.

After ranking third in points allowed in 2023, the 49ers dropped to 29th during Sorenson’s first season at the helm. The defense also struggled to generate turnovers, with Cam Inman of the Mercury News noting that the team had zero interceptions over their final seven games and only one fumble recovery over their final 11 games.

There was hope that Sorenson would help guide the 49ers to a new level after the team fired Steve Wilks last offseason. The former NFL journeyman moved quickly through the coaching ranks in San Francisco, where he worked his way up from a defensive assistant to defensive pass game specialist to defensive coordinator in three seasons. In addition to his one-year stint as Jaguars ST coordinator, Sorenson also had experience coaching defense with the Seahawks, where he served as the team’s secondary coach during the final seasons of the Legion of Boom era.

While the 49ers dealt with a long list of injuries, the team clearly wasn’t willing to tolerate the clear regression from the defense in 2024. Now, the organization will be seeking their fourth defensive coordinator in four seasons. Prior to Wilks one-year stint as defensive coordinator, DeMeco Ryans spent two years in the role before becoming head coach of the Texans.

Ryans’ predecessor, Robert Saleh, could be a candidate to take over for Sorenson, as Inman notes. Saleh spent four years as San Francisco’s defensive coach before leaving to become the Jets head coach in 2021. He was canned by the Jets earlier this season before catching on as a consultant in Green Bay, and he’s already emerged as a candidate for the Jaguars head coaching vacancy. It’s more likely that Saleh’s return to coaching will require a stop as coordinator, and a familiar spot in San Francisco could be his softest-possible landing.

Inman also points to Jeff Ulbrich and Gus Bradley as potential candidates for the 49ers new DC opening. Ulbrich most recently served as Saleh’s interim replacement in New York, and that was preceded by a three-plus-year stint as the Jets DC. The veteran coach crossed paths with Shanahan in Atlanta, and he spent his entire 10-year playing career in San Francisco.

Bradley and Shanahan have never worked alongside each other, but the veteran coach brings plenty of experience. Bradley most recently served as the Colts defensive coordinator, a role he held for three seasons before getting dismissed yesterday. Bradley also held DC roles with the Raiders, Chargers, and Seahawks, and he had a four-year stint as head coach with the Jaguars.
