NFL Network’s Tom Pelissero reported that the 49ers interviewed former Green Bay Packers linebackers coach and new Jacksonville Jaguars defensive coordinator Anthony Campanile

Saleh, who was fired in October as the New York Jets head coach five games into his fourth season, generated interest on the head-coaching front and was seen as one of the frontrunners for the Jacksonville Jaguars job. He also interviewed with the Las Vegas Raiders and Dallas Cowboys.

San Francisco 49ers head coach Kyle Shanahan is welcoming 49ers defensive coordinator Robert Saleh back to the same role, per NFL Media. Saleh served as Shanahan's original 49ers defensive coordinator for four seasons from 2017 to 2020,

There’s an interesting wrinkle to the San Francisco 49ers’ re-acquisition of defensive coordinator Robert Saleh. While they’re gaining an experienced defensive coordinator with a strong track record, they may also gain another opportunity to secure a pair of third-round draft picks if he’s hired to be another team’s head coach.

Later on Thursday, then-Tampa Bay Buccaneers offensive coordinator Liam Coen had a change of heart, the Jacksonville Jaguars quickly moved to hire him as head coach and Saleh, who told Kyle Shanahan and John Lynch that he’d return to the 49ers if he didn’t get a head-coaching job, stayed true to his promise.

The biggest concern surrounding the San Francisco 49ers' reunion with Robert Saleh is the possibility of him becoming the team's third consecutive one-and-done defensive coordinator.
