The 49ers this week fired head strength and conditioning coach Ray Wright, multiple sources told NBC Sports Bay Area.
The 49ers plan to restructure the strength and conditioning department, according to the sources, and the status of the remainder of the staff remains unclear.
The 49ers were plagued by injuries during the two seasons Wright served as head strength and conditioning coach under Kyle Shanahan. The club finished with records of 6-10 in 2017 and 4-12 in 2018.
This season, 17 players spent time on injured reserve, including quarterback Jimmy Garoppolo and running back Jerick McKinnon, who sustained torn ACLs.
