After just one season as the 49ers defensive coordinator, Nick Sorensen has been fired and will not be retained on the coaching staff in another capacity. Head coach Kyle Shanahan expressed a desire to keep Sorensen as the special teams coordinator.

The Dallas Cowboys are expected to hire Nick Sorensen as their new special teams coordinator, per Tom Pelissero of NFL Network. Sorensen will replace John “Bones” Fassel, who left the Cowboys to coach special teams for the Tennessee Titans.

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.
