HOUSTON -- The 49ers will not retain Mark Uyeyama, who served nine seasons on the team’s strength and conditioning staff, league sources told CSNBayArea.com on Thursday morning.

Uyeyama worked the past two seasons as the 49ers’ director of human performance and implemented many sports science practices even before the arrival coach Chip Kelly last season.

Uyeyama was originally hired in 2008 to serve as assistant strength and conditioning coach, a role in which he spent three seasons. He was promoted to head strength and conditioning coach in 2011, and was named Samson Equipment’s NFL Strength & Conditioning Coach of the Year by American Football Monthly in 2011.

As director of human performance, Uyeyama designed a position-specific training regimen for all players, including analytical data monitoring and nutrition. He assisted in the rehabilitation of injured players. The 49ers finished the season with 19 players on injured reserve.

Uyeyama served under head coaches Mike Nolan, Mike Singletary, Jim Harbaugh, Jim Tomsula and Kelly. It is not known whether other members of the 49ers strength and conditioning staff will be retained.

The 49ers on Sunday hired general manager John Lynch. Atlanta Falcons offensive coordinator Kyle Shanahan is in line to become the team’s next head coach after facing the New England Patriots on Sunday in Super Bowl 51. Although Uyeyama remained in his position through four coaching changes, it is common for new coaches to hire their own strength-and-conditioning coaches.
