Birmingham-born Roberts joined the Saddlers in 2014, following a recommendation by club legend Martin O'Connor, and, after enjoying a successful two-year scholarship signed pro terms in 2016, going on to make his first-team debut in December of the same year as Walsall and Oxford United played out a goalless draw.
After making another twenty-eight appearances over the next eighteen months Kory was sidelined after suffering double leg fracture as the Saddlers faced Stoke City in a friendly ahead of the 2018/19 campaign.
Forced to sit out the next fourteen months, Kory was finally able to get back on the pitch earlier this season, the defender replacing then on-loan Salford City striker Rory Gaffney for the final moments of the Saddlers EFL Trophy group stage victory over Southampton's Under-23s.
After making a total of four appearances during the curtailed 2019/20 campaign Kory was never able to secure a regular spot in the team and, despite being seen as a major prospect by both fans and club officials alike, was named among Darrell Clarke's 'Released and Retained' last week.
The 22-year-old defender, who is unlikely to struggle to find a new club, sought to thank former Saddlers boss Jon Whitney for handing him his debut, before also thanking his family, friends and fans.
Speaking via his official Instagram feed, Kory expressed his sadness at the prospect of leaving the club, he said; "I just want to thank everybody associated with Walsall FC for all of their support.
"A huge appreciation goes out to Jon Whitney for giving me the opportunity to showcase my talents. My league debut against Oxford will remain with me forever, and I owe that to the manager at the time.
"My first season playing for Walsall was a memorable one. To be named the Young Player of the Season was an unbelievable feeling and provided hope for the following season.
"Unfortunately, as many of you know, I sustained a double leg break in pre-season which saw me miss 14 months of doing what I love. Behind the scenes, everyone at Walsall, my friends and family supported me through this.
"I am sad to be leaving such a wonderful club with fantastic team spirit and great potential. Finally I want to thank the fans! You have been amazing throughout my journey as a Walsall player and I can't thank you enough.
"Continue to be loud and proud as you always are! I wish Walsall FC, and everyone involved, every success in the future."
