Town have told third-choice goalkeeper Cody Cropper that he won’t be offered a new contract at the end of the season. The US U20 international's current one-year deal is up at the end of June.
Cropper tweeted his disappointment: "It’s honestly so depressing but at the same time it’s good to know that I can move on to bigger and better things.”
The 19-year-old, who has missed much of the campaign due to a knee injury, joined the Blues’ Academy on a two-year scholarship in the summer of 2010.
As he was a year older than is usually the case for scholars, he signed a one-year professional contract last summer while he completed his time at Playford Road.
He has been on the first-team bench on three occasions, most recently at Crystal Palace 10 days ago, but never made a senior appearance.
The 6ft 3in tall Atlanta-born stopper, whose father is English, impressed the Town youth set-up in trials during 2009/10, having previously spent similar spells at Leicester, Arsenal, Birmingham, Portsmouth, Wolves and West Ham.
