The 49ers will be searching for a new defensive coordinator for the third year in a row after they relieved Nick Sorensen of his duties. Here is why.

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.

The 49ers removed Nick Sorensen from his role as defensive coordinator Tuesday night but hope to retain him in a different post, a source said.
