Mark Uyeyama, who’s been part of the 49ers’ strength and conditioning program under their past five head coaches, won’t last through another coaching transition.

Uyeyama will not return for a 10th season with the club, a league source confirmed Thursday following a report by CSN Bay Area.

The 49ers are expected to hire Kyle Shanahan as coach after Sunday’s Super Bowl, once he concludes his duties as the Atlanta Falcons offensive coordinator.

Uyeyama left the college ranks to join the 49ers in 2008 under then-coach Mike Nolan as the assistant strength and conditioning coach. After Nolan and Mike Singletary’s departures as coach, he was elevated to head strength coach under Jim Harbaugh. Uyeyama’s title the past two seasons was director of human performance.

Injuries took a tool on the 49ers the past few years, with 20 players going on injured reserve since training camp this past season, which was the same total they had in 2014.
