In what has become a season of almost constant change and turnover, the San Francisco 49ers announced Tuesday that Johnnie Lynn, the team's special assistant to the head coach/secondary, has resigned for personal reasons.
The 49ers did not name a replacement, but Matt Maiocco of CSN Bay Area reported that secondary coach Vance Joseph had taken over most of the coaching responsibilities this season.
Lynn, 53, had been with the team since 2006 and was in his 17th season in the NFL. He was also the 49ers secondary coach in 1996 under coach George Seifert.
Lynn is the second member of coach Mike Singletary's staff to leave. On Sept. 27, offensive coordinator Jimmy Raye was dismissed and replaced by quarterbacks coach Mike Johnson.
In addition, running back Glen Coffee abruptly retired in training camp, defensive tackle Kentwan Balmer went AWOL in camp and was later traded and safety Michael Lewis asked for and was granted his release in October.
