Kendrick left WWE again in 2009. Following his departure, he wrestled in different promotions, including TNA and NJPW. However, in 2014, Kendrick signed with WWE to become a trainer at the performance center. Shortly after, he returned to in-ring competition.
Kendrick mainly competed on 205 Live. The 42-year-old captured the Cruiserweight Championship in October 2016 before losing it to Rich Swann a month later.
Kendrick competed for the last time nearly a year ago when he teamed up with Mansoor to defeat Chase Parker and Matt Martel on 205 Live.
Last April, the former WWE Tag Team Champion confirmed his retirement in a video package titled Brian Kendrick: Life After Wrestling. The 42-year-old currently works as a backstage producer in WWE.
