49ers head coach Kyle Shanahan gave Saleh his first defensive coordinator opportunity in 2017 during Shanahan’s first season at the helm in San Francisco. Saleh struggled out of the gate, but turned into one of the NFL’s best defensive coordinators and wound up getting a job as the Jets head coach after the 2020 campaign.

For the second time in less than 11 months, the San Francisco 49ers are in the market for a new defensive coordinator.  According to NBC Sports Bay Area, the 49ers have decided that Nick Sorensen won't be returning as the team's defensive coordinator in 2025.
