Charlton can confirm that Charlie Kirk has left the club by mutual consent.
The winger joined the club in the summer of 2021 and played 48 games for the Addicks, scoring four goals.
Technical Director Andy Scott said: “Unfortunately it hasn’t worked out for Charlie during his time here and he’s not been playing regular first-team football.
"We’ve come to an amicable agreement that frees up a bit of space ahead of the January window and allows Charlie to go and find a suitable opportunity to get back to enjoying playing regular football again. We wish him the very best for the future.”
