The 49ers have not retained any members of the team’s strength and conditioning staff, the club confirmed on Tuesday.
The 49ers official website no longer lists director of human performance Mark Uyeyama; strength, conditioning and nutrition assistant Kurt Schmidt; and strength and conditioning assistants Brian Johnson, Taylor Johnson and David Young.
The 49ers will bring in a new strength and conditioning staff under new coach Kyle Shanahan and general manager John Lynch.
The organization's decision to release Uyeyama was reported last week. Uyeyama served nine seasons with the 49ers under head coaches Mike Nolan, Mike Singletary, Jim Harbaugh, Jim Tomsula and Chip Kelly.
Schmidt spent four seasons with the organization after working as strength and conditioning coordinator at Arkansas from 2008 to '12. He worked at Utah State with Uyeyama from 2006 to '07.
Young was with the 49ers for three seasons. Brian Johnson was recently hired at Texas A&M after spending two seasons with the 49ers. Taylor Johnson, who has spent the past two seasons with the club, is a possibility to remain with the new staff, a source said.
