Robert Saleh’s encore as 49ers defensive coordinator took on more likelihood as the Jacksonville Jaguars and the Las Vegas Raiders hired others to fill their head coach vacancies.

SANTA CLARA, Calif. — Robert Saleh is reprising his role as the 49ers’ defensive coordinator, the team announced Friday night. Saleh returns to a vastly different unit than he left behind four years ago.

The San Francisco 49ers are bringing back Robert Saleh for a second stint as defensive coordinator after a failed tenure as head coach of the New York Jets.

Robert Saleh, who ran the Niners' defense from 2017 to 2020, is heading back to San Francisco for the same role after a three-plus-year stint as Jets coach.

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.

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

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.
