talkSPORT Football reports that the 29-year-old failed to appear in any of Charlton's opening Championship games, and his game time was likely to further reduce with Skipp's addition to the squad.
Docherty, who was the club captain, made 90 appearances for Charlton since joining the club from Hull City in the summer of 2024. He helped the Addicks to promotion to the Championship in his debut season and leaves behind an "incredible group of teammates, staff and people behind the scenes" at The Valley.
The former skipper has expressed his gratitude to the club and its fans, stating that he is "devastated to be leaving" but "excited to see what the future holds".
