Originally an undrafted free agent by the Cleveland Browns in 2011, he appeared in 12 games as a rookie with no starts. He then joined the Panthers where he spent the past three seasons.
The California native grew up a Raiders fan and jumped at the chance to sign with them this offseason as a free agent. He appeared in 31 games in his four-year career with two starts in Carolina. Without a great many options for corners on the market, Dockery was the Raiders' only free agent cornerback addition.
Following his release, Dockery put this message on his Instagram account:
"Walk by Faith and not by Sight! Thank you for allowing me to live out one of my dreams of playing in the black and silver. If this is it, it's been a hell of a ride. Thank you to all who supported my efforts and especially thank you to all of #RaiderNation you guys are truly a wonderful fan base full of energy and passion. Good luck this year #4one"
