Town have confirmed that Polish central defender Piotr Malarczyk has left the club having had his contract terminated by mutual consent.
Malarczyk joined the Blues a year ago today from his hometown club Korona Kielce, where he was skipper, Town triggering a release clause in his contract which allowed him to move on if a foreign side made an offer of 50,000 zloty (around £8,500).
The 25-year-old made only three cup starts - including the FA Cup replay at Portsmouth in which he was red-carded - and three Championship sub appearances, all last season, and joined Southend on loan for the final weeks of the campaign having been made available for transfer.
