SANTA CLARA, Calif. — Season No. 9 for 49ers coach Kyle Shanahan comes with his staff’s most significant overhaul.

New coordinators are in place: Robert Saleh returns to the defense after three-plus seasons as the New York Jets coach, Brant Boyer leaves his post with the Jets to oversee the 49ers’ troubled special teams, and Klay Kubiak gets promoted on offense, where plays still will be called by Shanahan.

In a surprise, Brian Griese has been replaced after three years as quarterbacks coach by Mick Lombardi, who returned to Shanahan’s staff a year ago as a senior offensive assistant.

Griese has been a staunch advocate and mentor of Brock Purdy since his 2022 arrival as the NFL draft’s last pick. Shanahan also interviewed D.J. Williams for quarterbacks coach, a role he’s now in with the Atlanta Falcons.

With Shanahan absent from the NFL scouting combine for a fifth straight year, general manager John Lynch is expected to address Griese’s status and other changes when meeting with reporters Wednesday in Indianapolis. Lynch’s son, Jake, was hired onto Shanahan’s staff as a defensive quality control coach after spending last season as a Washington graduate assistant.

Gus Bradley, most recently the Indianapolis Colts’ defensive coordinator, will carry the title of assistant head coach/defense under Saleh. Chris Foerster will add the title of assistant head coach/offense to his duties as offensive line coach.

Other changes to the staff: Ray Brown (defensive backs/cornerbacks), Ronald Blair III (special teams quality control), Colt Anderson (special teams assistant), Joe Graves (offensive assistant/quarterbacks), Leonard Hankerson (wide receivers, plus pass-game specialist), Andrew Hayes-Stoker (offensive assistant/wide receivers), Greg Scruggs (assistant defensive line), Jacob Webster (offensive quality control) and Patrick Hagedorn (chief of staff, football).

Although Shanahan prematurely announced Kubiak’s promotion at his season wrapup press conference last month, the league’s minority-hiring guidelines were satisfied with Shanahan’s subsequent interviews with Noah Pauley of Iowa State and Junior Adams, a former Amador Valley High-Pleasanton product who’s since been hired as the Dallas Cowboys wide receivers coach.

Only three coaches in the NFL have held their job longer than Shanahan: Mike Tomlin (Pittsburgh Steelers, 18 years), John Harbaugh (Baltimore Ravens, 17 years) and Andy Reid (Kansas City Chiefs, 12 years).

Here is a list of coaching and front office moves around the NFL heading into next season, which culminates with Super Bowl LX at Levi’s Stadium:
